Update default fmask from 0077 to 0177 for EFI system partitions when mounting. Using 0177 aligns with systemd defaults while preventing non-executable file bit permissions and satisfying bootctl requirements. Fixes archlinux#4714

Fixes #4714
Context & Rationale
When setting default mount options for the EFI system partition,
fmask=0077was previously used. Updating this tofmask=0177ensures files on the ESP are not created with execute permissions, while keepingdmask=0077for directories. This aligns with systemd's default behavior for ESP mount options (fmask=0177,dmask=0077) and satisfiesbootctlrequirements.Changes
