3 more test-changes

[Jim Meyering]

FYI, there were a few minor problems.
Running "make check" in the background would hang
and the new install-C test would fail in a directory with
the setgid bit set.

I've fixed the first, but since I'm not sure "trap '' TTOU" is
portable the second change-set just makes it so all three of the
affected tests are skipped unconditionally.  I'll revert c-set #2
right after release.

The third just skips the install-C test when necessary.

Subject: [PATCH 1/3] tests: don't let SIGTTOU/TTIN hang a backgrounded "make 
check"

Running "make check &" would hang due to SIGTTOU and SIGTTIN signals.
* tests/misc/stty: Ignore SIGTTOU.
* tests/misc/stty-invalid: Likewise.
* tests/mv/i-3: Ignore SIGTTIN.
