tmpfs: support for file creation time

Various filesystems (including ext4) now support file creation time.
This adds such support for tmpfs-based filesystems.

Note that using shmem_getattr() on other file types than regular
requires that shmem_is_huge() check type, to stop incorrect
HPAGE_PMD_SIZE blksize.
