fs/vfs: inherit ownership in pseudofile_create

Browse source 
Initialize i_owner and i_group from the creating task's
effective uid/gid when a pseudo-file is created via O_CREAT.

This aligns pseudo-file ownership with the creator's
effective credentials instead of leaving new files
root-owned by default.
