Remove support for experimental patches and musl patches

This functionality was provided so that crosstool-ng could have a
further set of patches considered experimental and unsupported.
Now that musl-libc support is making it's way upstream in gcc, I'm
removing this support and the experimental musl patches.

In later commits, backports from gcc upstream will be added to the
supported patch sets to support musl-libc.
