run-tests: make sure to check if pygments is installed before using it

e80041832e introduced support to color the output of tests but used pygments
without checking whether it's installed or not. That breaks test-run-tests.t for
machines which don't have pygments installed. This patch conditionalize the
color test in test-run-tests.t and also add a check to make sure pygments is
installed before using that.

This file tests the behavior of run-tests.py itself.

Avoid interference from actual test env:

  $ . "$TESTDIR/helper-runtests.sh"

Smoke test with install
============

  $ run-tests.py $HGTEST_RUN_TESTS_PURE -l
  
  # Ran 0 tests, 0 skipped, 0 failed.

Define a helper to avoid the install step
=============
  $ rt()
  > {
  >     run-tests.py --with-hg=`which hg` "$@"
  > }

error paths

#if symlink
  $ ln -s `which true` hg
  $ run-tests.py --with-hg=./hg
  warning: --with-hg should specify an hg script
  
  # Ran 0 tests, 0 skipped, 0 failed.
  $ rm hg
#endif

#if execbit
  $ touch hg
  $ run-tests.py --with-hg=./hg
  Usage: run-tests.py [options] [tests]
  
  run-tests.py: error: --with-hg must specify an executable hg script
  [2]
  $ rm hg
#endif

Features for testing optional lines
===================================

  $ cat > hghaveaddon.py <<EOF
  > import hghave
  > @hghave.check("custom", "custom hghave feature")
  > def has_custom():
  >     return True
  > @hghave.check("missing", "missing hghave feature")
  > def has_missing():
  >     return False
  > EOF

an empty test
=======================

  $ touch test-empty.t
  $ rt
  .
  # Ran 1 tests, 0 skipped, 0 failed.
  $ rm test-empty.t

=======================

  $ cat > test-success.t << EOF
