tar: -x -C symlink fix

Browse Source 
* src/misc.c (chdir_do): Don't use O_NOFOLLOW when opening the
argument to -C.  This is for consistency with "tar -c -C FOO", and
matches the new documentation.
* tests/extrac14.at: New file.
* tests/Makefile.am (TESTSUITE_AT): Add it.
* tests/testsuite.at: Include it.
