cygport test fails

[Achim Gratz]

At least on my system, when I test the built cygport through cygport
itself, I get lots of test fails due to:

/mnt/share/packages/cygport.noarch/src/rpm-style/lib/src_fetch.cygpart: line 153: git_fetch: command not found

When I run the tests manually, that doesn't happen.  I've verified this
error occurs because I build cygport from git, so that function is
already defined by the outermost cygport (and declared unmutable).  It
seems that the test driver should start a fresh cygport instance to
decouple the two shell environments, but I didn't really get why the
environment bleeds into the test in this undesirable way to start with.

The rest of the test fail s is either me not having installed some stuff
that would be needed or file names that differ only in case, like so:

--8<---------------cut here---------------start------------->8---

It seems that the expected outputs need updating or else the comparison
should be done case-insensitively by default?  The test-driver script
already has provisions for that, so these fails vanish if I export

CASE_INSENSITIVE=1

in the cygport file, but I guess something more targeted would be
better.
