Bug 1409895 - Deny getcwd in the Linux content process sandbox. r=gcp getcwd won't do anything useful once we start chroot()ing to remove filesystem access; with this patch it will at least fail the same way regardless of whether user namespaces are available or if other factors prevent complete FS isolation. Bonus fix: improve the comments for this group of syscalls. MozReview-Commit-ID: KueZzly2mlO
