Subject: [PATCH] Gentoo: override paths for system-wide install based on
 sys.prefix

Override all default distutils install paths to ones suitable for
system-wide install when sys.prefix indicates we're running the Gentoo
system-wide install of PyPy with no prefix overrides (e.g. virtualenv).

Fixes: https://bugs.gentoo.org/465546
