Fix tests when logical and physical CWD differ

MH testsuite produced false negatives when run in a directory accessed
by its logical name (symlink).  To fix this, avoiding at the same time
the use of non-portable "pwd -P" & "pwd -L", this commit adds a filter
utility that replaces both logical and physical cwd with a dot on
output.  The MH testsuite is updated to use this utility.

* testsuite/cwdrepl.c: New utility
* testsuite/Makefile.am: Build cwdrepl
* testsuite/.gitignore: Update.
* testsuite/cwdrepl.at: New test.
* testsuite/testsuite.at: Include new test.

* mh/tests/atlocal.in (PATH): Add testsuite
(remove_curdir): Remove function.
* mh/tests/comp.at: Use cwdrepl, fix expected output.
* mh/tests/forw.at: Likewise.
* mh/tests/mhn.at: Likewise.
* mh/tests/mhpath.at: Likewise.
* mh/tests/repl.at: Likewise.
