objtool, kcsan: Add explicit check functions to uaccess whitelist
Add explicitly invoked KCSAN check functions to objtool's uaccess
whitelist. This is needed in order to permit calling into
kcsan_check_scoped_accesses() from the fast-path, which in turn calls
__kcsan_check_access(). __kcsan_check_access() is the generic variant
of the already whitelisted specializations __tsan_{read,write}N.
