Make into user-friendly

The script was meant to be a wrapper around QEMU that parses the result
of a kvm-unit-tests' instance from the logs. Make the script more useful
for users by adding new command-line flags and making most flags

Users can now run a single test case without having to wait for Make to
check if dependencies need to be rebuilt, run a test case with GDB
enabled, while still being able to provide a custom kernel and/or pass
flags directly to QEMU.

Example usage:
  $ make -j40
  $ build/kvm-unit-tests/ -G psci # run with GDB
