Set locale related environment variables in debugglibc.sh

  From: Arjun Shankar <arjun@redhat.com>

Tests and binaries that use locale related functions need to run in the
correct locale environment when being debugged via debugglibc.sh. This
commit sets up the environment, specifically: GCONV_PATH, LOCPATH, and
LC_ALL for such tests and binaries when they are being debugged outside
of a test container.

Agreed. And any non-SUPPORTED locales can be built outside of the container
and then installed by the container script. We should try hard to make the
container tests look like normal installs.

OK.

OK.

`==' is non-POSIX.

Thanks, Andreas. I'll replace with `='.

The whole of debugglibc.sh is a bash script and as such may use bash
constructs, and indeed has other instances of '=='.

However, there is value in simplifying this to make it POSIX shell
compatible.
