scripts/env_use_destdir: fix Fedora support

libselinux and libsemanage use:

    PYTHONLIBDIR ?= $(shell $(PYTHON) -c "from distutils.sysconfig
    import *; print(get_python_lib(plat_specific=1,
    prefix='$(PREFIX)'))")

while python/semanage and python/sepolgen/src/sepolgen use:

    PYTHONLIBDIR ?= $(shell $(PYTHON) -c "from distutils.sysconfig
    import *; print(get_python_lib(prefix='$(PREFIX)'))")

This is right: libselinux and libsemanage's Python bindings use native
code (thus "plat_specific=1") while the others only install Python
files.

Nevertheless `scripts/env_use_destdir` only runs the second command
when computing `$PYTHONPATH`. When using this script to run `make test`
in a minimal Fedora 31 environment, this leads to an error such as:

    make[2]: Entering directory '/code/python/sepolicy'
    Traceback (most recent call last):
      File "test_sepolicy.py", line 117, in <module>
        import selinux
    ModuleNotFoundError: No module named 'selinux'

Fix this by also adding `get_python_lib(plat_specific=1)` to the
computed `$PYTHONPATH`.

While at it, preserve `$PYTHONPATH` instead of resetting it. This makes
it easier to work with Python virtual environments.
