dev-python/pypy-bin: Apply full Gentoo path set, for Gentoo sys.prefix

Override all default distutils.command.install paths for Gentoo rather
than just scriptdir. However, do that only when install_base equals
the default prefix in which PyPy is installed system-wide.

This fixes both issues resulting from lack of prefix override (like
installing data files in /usr/lib*/pypy), and from overeager prefix
overrides (like virtualenv installing scripts in /usr/bin).

+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).
