[PATCH 4/4] tests: skip perl tests if NO_PERL is defined

[Jeff King <peff@peff.net>]

These scripts all test git programs that are written in
perl, and thus obviously won't work if NO_PERL is defined.
We pass NO_PERL to the scripts from the building Makefile
via the GIT-BUILD-OPTIONS file.

Signed-off-by: Jeff King <peff@peff.net>

This touches every test that Robin's patch touched except for
t5505-remote. There is no need to skip those tests, as these days
"git remote" is a builtin.
