[ Upstream commit e51bd0e595476c1527bb0b4def095a6fd16b2563 ]
Commit c6d9775c2066 ("selftests/fs/mount-notify: build with tools include dir") introduces the struct __kernel_fsid_t to decouple dependency with headers_install. The commit forgets to define a macro for __kernel_fsid_t and it will cause type re-definition issue.
