t/t1517: mark tests that fail with GIT_TEST_INSTALLED

The changes added by 39fc408 (t/t1517: automate `git subcmd -h` tests
outside a repository, 2025-08-08) to automatically loop over all "main"
Git commands will, when run against an installed build using
GIT_TEST_INSTALLED rather than the build in the build directory, include
some extra git-gui commands that are installed by `make install`, or
credential helpers that might be installed manually from the contrib
directories.  These fail the test, so record them as such.
