Instead of having to create files, and copying them in place for each
test, we move all static test files to a skeleton rootfs. This makes
it a lot easier to get an overview of how things and how they work.

serv: add support for foregrounding, running with and without PID file,
including custom PID filename.
test: verify Finit can start & monitor services that:
1) Fork and creates a PID file in a known location
2) Don't fork and don't create a PID file, but Finit does
3) Don't fork but create a PID file
4) Don't fork and create custom named PID file
Note: Finit cannot support a service that forks and doesn't create a PID
file. This combination is impossible to support without tracking
all processes created in /proc -- which Finit does not do atm.

Coding style for shell scripts:
- Tabs for indent (change in Emacs needed)
- Braces on their own line, like C functions

Install start-stop-daemon in test root. Add S01-service.sh, which uses
start-stop-daemon to start service.sh. Modify service.sh to respect
signals, and not exit immediately when sleep exits due to SIGTERM.
Remove PID file in signal callback and make sure to exit OK
The test itself is basically a copy of the start-stop-service.sh test.

The slay script checks for common errors and gives some logs and status
of Finit when something goes wrong. Helps detect issue #226 when the
start-kill-service.sh test runs at 100000 laps.

This commit implements a test for the signal feature of initctl. The
existing service used in tests (`common/service.sh`) has been extended
with a signal trap handler. When SIGUSR1 is received, it will write the
string `'USR1'` to `/tmp/usr1.log`. The test will run `initctl signal
service.sh SIGUSR1` and assert that the contents of the file
`/tmp/usr1.log` really is `USR1`.
We extend the service.sh to emulate a well behaving service that creates
and removes its own PID file.
The new test emulates a crash by sending SIGKILL to service.sh. We then
verify that Finit restarts it, and eventually registers the new PID when
the services recreates the PID file.
Issue #226
