Changed the sky130 and gf180mcu Makefiles so that "--with-reference"
works as advertised, which is that "--with-reference" by itself
uses the exising "sky130.json" or "gf180mcu.json" file, while
"--with-reference=<file>" uses "<file>" to get the source
repository commit hashes (and without the argument, the latest
version of all repositories is used).  Previously, the version
"--with-reference=<file>" did not work at all, and was equivalent
to not using the argument.  Thanks to Toni Trigoso for pointing
out the error.
