dev-libs/bglibs: update EAPI 7 -> 8

  * Delay ${ED} substitution until src_install
  * Add a patch to fix the build on musl
  * Add a patch to fix feature detection

This doesn't fix all of the problems with this package, but it's a
start. We have at least two users working on this in addition to
myself. No one has been able to get their patches merged because the
other problems always prevent the reviewers from testing. So I am
partially resolving the Catch 22.
