tests: remove obsolete PYTHONPATH override from remotefilelog tests

They were added in
https://bitbucket.org/facebook/hg-experimental/commits/fdcad37a6a68cfbaf5920f3eeaa0cc9cae42bd26,
which says this:

  When remotefilelog moved from its own repo, the tests needed to be updated to
  adjust the PYTHONPATH to ensure the in-repo remotefilelog was loaded instead of
  the system one.

  This meant any local runs of remotefilelog tests would've been using the system
  remotefilelog unless the user had manually set the PYTHONPATH themselves.

That doesn't seem relevant with remotefilelog in core.

Create 2 heads containing the same file, once as
a file, once as a link. Bundle was generated with:

# hg init t
# cd t
# echo a > a
# hg ci -qAm t0 -d '0 0'
# echo l > l
# hg ci -qAm t1 -d '1 0'
# hg up -C 0
# ln -s a l
# hg ci -qAm t2 -d '2 0'
# echo l2 > l2
# hg ci -qAm t3 -d '3 0'

  $ hg init t
  $ cd t
  $ hg -q unbundle "$TESTDIR/bundles/test-merge-symlinks.hg"
  $ hg up -C 3
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Merge them and display *_ISLINK vars
merge heads

  $ hg merge --tool="\"$PYTHON\" ../echo.py"
