This is a change with far-reaching effects on MS-Windows at the least,
where file-related APIs are shadowed to support transparent support
for UTF-8 encoded file names. Making such changes on a stable branch
for the benefit of a proprietary platform with a 13-year old OS is a
tail wagging the dog. Please don't do that without discussing first.

Fix GC bug in filelock.c
Fix a bug where if GC occurred at the wrong moment when locking a
file, the lock file’s name was trashed so file locking did not work.
This bug was introduced in Emacs 28.1. The bug sometimes caused
filelock-tests-detect-external-change test failures on Fedora 35
x86-64 in an en_US.utf8 locale.
* src/filelock.c (lock_file_1, current_lock_owner, lock_if_free)

Use Lisp_Object, not char *, for string, so that GC doesn’t trash
string contents.
