Do not pass unsupported mount options to the kernel.
The filesystem daemon is responsible for implementing eg. st_atime updates, so passing
options like relatime to the kernel results in them being silently ignored. Instead, such
options need to be interpreted (and filtered out) by the filesystem daemon.
