Subject: [PATCH] modules/python.py: do not substitute python's install prefix
 with meson's

Not sure why this is being done, but it
a) relies on Python's internal variable substitution which may break in the future
b) shouldn't be necessary as Python's prefix ought to be correct in the first place

Upstream-Status: Pending
