maint: don't assume GNU make \# syntax

* src/Makefile.am (fs_normalize_perl_subst): Don't make unportable
assumption about \# in the right hand side of a macro definition.
This works with GNU make, but not with POSIX make.
Problem reported by Basavaraj B (Bug#10220).
(fs-magic, fs-kernel-magic): Do the #-substitution here instead.
