Subject: fusefrontend: expose birth time via statx

Forward the backing filesystem's STATX_BTIME on Linux while preserving
existing metadata translations and fallback behavior.

On Linux 6.6 and newer, this allows statx consumers such as GNU stat
to report birth time when the backing filesystem provides it. Older
kernels and backing filesystems without birth-time support retain the
existing behavior. No on-disk format change or migration is required.

Reverse mode remains unchanged.

Fixes #868.
