arm64: idreg-override: Avoid parameq() and parameqn()

Browse source

The only way parameq() and parameqn() deviate from the ordinary string
and memory routines is that they ignore the difference between dashes
and underscores.

Since we copy each command line argument into a buffer before passing it
to parameq() and parameqn() numerous times, let's just convert all
dashes to underscores just once, and update the alias array accordingly.

This also helps reduce the dependency on kernel APIs that are no longer
available once we move this code into the early mini C runtime.
