python-utils-r1.eclass: Fix PYTHON_SITEDIR/INCLUDEDIR for cross-prefix
We dynamically determine Python's SITEDIR and INCLUDEDIR using the build
host's Python. This breaks down when the build host's prefix differs
from the target host's prefix, so chop off the former and prepend the
latter.
This assumes that each Python implementation is always installed using
the same scheme. Meson already makes this assumption, and gpep517 makes
a similar assumption to determine Python's stdlib location.
We could improve on this and determine these locations using SYSROOT's
sysconfigdata file, like gpep517 does, but this seems needlessly
complex. We would need to take this approach for PYTHON_LIBPATH and
PYTHON_CONFIG, but these are only used by handful of packages.
${BROOT-${EPREFIX}} is needed rather than plain ${BROOT} for the same
reason we need it for PYTHON, namely that Portage <3.0.50 was buggy.
