On systems using non-default `PREFIX`, `LIBDIR`, `SHLIBDIR`, `BINDIR`
or `SBINDIR`, running
`DESTDIR=/path/to/destdir ./scripts/env_use_destdir make test`
does not perform the intended behavior, because the testing programs and
libraries are installed into locations that are not added to
`LD_LIBRARY_PATH` nor `PATH`.
More precisely, with `LIBDIR=/usr/lib64 SHLIBDIR=/lib64`, `env_use_destdir`
does not work. Fix this by adding the installation directories relative
to `DESTDIR` in `LD_LIBRARY_PATH` and `PATH`.

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.

- Python 2.7 is planned to be the last of the 2.x releases
- It's generally advised to use Python 3
- Majority of python/ scripts are already switched python3
- Users with python 2 only can still use:
$ make PYTHON=/usr/bin/python ....

Set-up environment variables in order to use DESTDIR in Python, Ruby,
etc. This makes testing Python scripts easier.
