Prevent name clash with upcoming refactor and any confusion with
src/plugin.c functions with the same name.

There exist two possible basename functions, a xpg compliant one in libgen.h
and a GLIBC exclusive one declared in string.h, that was previously also declared by musl libc.
Both implementations are expecting different parameter types (`const char *` for GLIBC and `char *` for xpg)
With the removal of the basename function from string.h in musl libc, we could only rely on the xpg implementation.
Unfortunately, the xpg implementation of basename does modify the contents of whatever you put in it,
even though that there really is no need for it.
This is an issue in some cases, where we might want to get the basename of a read-only variable, e.g. a `const char *`,
as trying to modify something read-only is undefined behavior.
So in order to keep things consistent for us, we implement our own version of basename called `basenm`,
that does not modify the passed argument.
As it turns out, not all buses in Linux will add `modalias` attributes
to their devices in sysfs. One notable exception are MDIO buses. The
plugin's scan routine would thus not pick them up.
Fortunately, the information is always available in the device's
`uevent` attribute.
Therefore, default to looking for modaliases in the device's `uevent`
attribute instead, falling back to `modalias` only if `uevent` is not
availble (this should never happen).
initctl cannot link with helpers.c, so let's relocate these helper
functions to util.c instead. Need them to probe for cgroup support.

Due to an unfortunate name clash with the DirectFB project LiTE, the
libite (-lite) project had to change its header namespace from
lite/*.h -> libite/*.h
This patch adds support for the new namepace in Finit, triggered by the
define _LIBITE_LITE, from the .pc file read by pkg-config. This should
only be needed on systems that install libite without the compatibility
symlink lite -> libite/ in the staging include directory.

Unlike find(1), nftw(3) defaults to follow symlinks. For some kernel
configurations this turned out to be detrimental and caused the plugin
to loop forever scanning modalias files.
Also, check if /sys is mounted before even calling nftw().

This patch adds a new plugin to Finit called modprobe. It probes in
/sys/devices after modalias files and then calls 'modprobe -ab' for
each alias listed.
For hot-plugging we recommend adding the following to /etc/mdev.conf
$MODALIAS=.* root:root 0660 @modprobe -b "$MODALIAS"
