Use ccache in builds

Add ccache support to the OsBase definition, so it's automatically setup for all
machines. Hopefully this can speed up builds and at least prevent the worst case
performance.

Unfortunately, if I modify the stdenv of any upstream targets, the cache is
invalidated and I have to rebuild the whole package. In particular webkitgtk is
a pain to build, and it has crashed my machine a number of times. I was able to
build it once, after enabling zram, which should be enabled anyway like why not?
