use fspathhash() everywhere

cf2dc1c238 (speed up alt_odb_usable() with many alternates, 2021-07-07)
introduced the function fspathhash() for calculating path hashes while
respecting the configuration option core.ignorecase.  Call it instead of
open-coding it; the resulting code is shorter and less repetitive.
