package/intel-microcode: make target installation optional

Browse Source 
For early microcode loading, there is no need to install the individual
microcode files to /lib/firmware - So make that optional.

Let the option default to y for backwards compatibility, and select it from
iucode-tool as the init script relies on the /lib/firmware files.
