run-tests: also follow symlink when update PATH with 'run-tests.py' dir

I'm using 'run-tests.py' from my '$PATH' and use a symlink to get 'run-tests.py'
to in that '$PATH'. There is a handful of test helpers (like f) that needs to be
in the '$PATH' for the test to run, and they are expected to live next to the
'run-tests.py' binary. Using a symlink confuses this logic, so we add to the
'$PATH' both the 'run-tests.py' executable directory, and the actual file
location direction.

import os
from mercurial import dispatch

def testdispatch(cmd):
    """Simple wrapper around dispatch.dispatch()

    Prints command and result value, but does not handle quoting.
    """
    print "running: %s" % (cmd,)
    req = dispatch.request(cmd.split())
    result = dispatch.dispatch(req)
    print "result: %r" % (result,)


testdispatch("init test1")
os.chdir('test1')

# create file 'foo', add and commit
f = open('foo', 'wb')
f.write('foo\n')
f.close()
testdispatch("add foo")
testdispatch("commit -m commit1 -d 2000-01-01 foo")

# append to file 'foo' and commit
f = open('foo', 'ab')
f.write('bar\n')
f.close()
testdispatch("commit -m commit2 -d 2000-01-02 foo")
