webos: gator-mod=r5.3 (gator_fs: Fix build with linux-6.6 and newer)

:Release Notes:
In Linux commit 13bc24457850583a2e7203ded05b7209ab4bc5ef, direct access
to the i_ctime member of struct inode was removed. The new approach is
to use accessor methods that exclusively handle passing the timestamp
around by value.

:Detailed Notes:
More details in e.g.:
darkbasic/zfs@0769c00
