cpupower: make systemd unit installation optional

Browse Source 
cpupower currently installs a cpupower.service unit file into unitdir
unconditionally, regardless of whether systemd is used by the host.

Improve the installation procedure by making this systemd step optional:
a 'SYSTEMD' build parameter that defaults to 'true' and can be set to
'false' to disable the installation of systemd's unit file.

Since 'SYSTEMD' defaults to true, the current behavior is kept as the
default.
