Fix insert-file-contents overlap calculation

* src/fileio.c (Finsert_file_contents): Overlap is impossible, so
omit incorrect overflow adjustments that caused later index
calculations to go off the rails (Bug#77315).  Change a ‘ZV_BYTE’
to ‘same_at_end’ for clarity; they have the same value here.

(cherry picked from commit 61a8ce0280668980a4452b112103c9bc879e1f49)
