run-tests: deal with distutil deprecation
PEP 632 recommend the use of `packaging.version` to replace the deprecated
`distutil.version`. So lets do it.

# Modifying this script is tricky because it has many modes:
# - serial (default) vs parallel (-jN, N > 1)
# - no coverage (default) vs coverage (-c, -C, -s)
# - temp install (default) vs specific hg script (--with-hg, --local)
# - tests are a mix of shell scripts and Python scripts
#
# If you change this script, it is recommended that you ensure you
# haven't broken it by running it in various modes with a representative
# sample of test scripts. For example:
#
# 1) serial, no coverage, temp install:
# ./run-tests.py test-s*
# 2) serial, no coverage, local hg:
# ./run-tests.py --local test-s*
# 3) serial, coverage, temp install:
# ./run-tests.py -c test-s*
# 4) serial, coverage, local hg:
# ./run-tests.py -c --local test-s* # unsupported
# 5) parallel, no coverage, temp install:
# ./run-tests.py -j2 test-s*
# 6) parallel, no coverage, local hg:
# ./run-tests.py -j2 --local test-s*
# 7) parallel, coverage, temp install:
# ./run-tests.py -j2 -c test-s* # currently broken
# 8) parallel, coverage, local install:
# ./run-tests.py -j2 -c --local test-s* # unsupported (and broken)
# 9) parallel, custom tmp dir:
# ./run-tests.py -j2 --tmpdir /tmp/myhgtests
# 10) parallel, pure, tests that call run-tests:
# ./run-tests.py --pure `grep -l run-tests.py *.t`
#
# (You could use any subset of the tests: test-s* happens to match
# enough that it's worth doing parallel runs, few enough that it
# completes fairly quickly, includes both shell and Python scripts, and
# includes some scripts that run daemon processes.)
