This change relocates phosphor-led-manager service files from the Yocto
layer to the phosphor-led-manager repository.
It also ensures that non-user executables are installed in the libexec.

/tmp/phosphor-led-manager/usr/local/libexec/phosphor-led-manager/phosphor-fru-fault-monitor
$ find /tmp/phosphor-led-manager -type f | grep service
/tmp/phosphor-led-manager/usr/lib/systemd/system/obmc-fru-fault-monitor.service
/tmp/phosphor-led-manager/usr/lib/systemd/system/obmc-led-group-start@.service
