rez executables aren't removed in windows install

[nerdvegas]

As part of the install process, rez cli tools are copied into a /rez subdir within the venv bin path - this is so that other unrelated exes (such as python) aren't accidentally run from rez's venv. See https://github.com/nerdvegas/rez/blob/master/install.py#L86-L90.

The specs.keys() returns a list like ['rez', 'rezolve', '_rez-complete', '_rez_fwd', 'rez-bind', 'rez-build', ...], but on windows the files all have the ".exe" extension. Meaning the line if os.path.isfile(filepath): always returns False, and those files never get deleted.

To Reproduce

1. perform an install on windows

Expected behavior
rez cli tools in root bin dir are deleted

Actual behavior
rez cli tools in root bin dir are not deleted
