run-tests: forward Python USER_BASE from site (issue5425)

We do this so that any linters installed via pip install --user don't
break. See https://docs.python.org/2/library/site.html#site.USER_BASE
for a description of what this nonsense is all about.

An alternative would be to not set HOME, but that'll cause other
problems (see issue2707), or to forward every single path entry from
sys.path in PYTHONPATH (which seems sketchy in its own way).

Test issue2761

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch does-not-exist-in-1
  $ hg add
  adding does-not-exist-in-1
  $ hg ci -m third
  $ rm does-not-exist-in-1
  $ hg diff -r 1
