Fix #250: support finit.cond=foo for cmdline <boot/foo> conditions

As a real life example, this can be useful for a mfgtest mode for the
device, wherein the bootloader can be set to finit.cond=test_mode or
finit.cond=user_mode and then specific services can start up in test
mode which wouldn't normally start.

Or even custom firmware update mode such as finit.cond=fw_update_mode
which performs some specific firmware update steps and doesn't launch
normal processes.
