[PATCH] t/t5800-remote-testpy: skip all tests if not built

[Ramkumar Ramachandra <artagnon@gmail.com>]

416fda6 (build: do not install git-remote-testpy, 2013-05-24) added
git-remote-testpy to NO_INSTALL, with the intent of excluding it from
the default install.  This is typically meant for scripts in contrib/
with their own testsuite and Makefile (e.g. git remote-bzr, git
remote-hg).  Unfortunately, git-remote-testpy.py is a toplevel script
without its own Makefile; its testsuite is located in
t/t5800-remote-testpy.sh.

What this means is that git-remote-testpy is not built by default (when
'make' is invoked), but t5800 runs by default (like every other test in
t/).  As a result, a new contributor cloning git.git and running 'make
test' for the first time will notice test failures.  Fix this
unpleasantness by patching t5800 to check for git-remote-testpy as a
prerequisite.
