The non-standard .fa library suffix breaks the link source
de-duplication done by Meson so drop it.
The lack of link source de-duplication causes AddressSanitizer to
complain ODR violations, and makes GNU ld abort when combined with
clang's LTO.
Fortunately, the non-standard suffix is not necessary anymore for
two reasons.
First, the non-standard suffix was necessary for fork-fuzzing.
Meson wraps all standard-suffixed libraries with --start-group and
--end-group. This made a fork-fuzz.ld linker script wrapped as well and
broke builds. Commit d2e6f9272d33 ("fuzz: remove fork-fuzzing
scaffolding") dropped fork-fuzzing so we can now restore the standard
suffix.
Second, the libraries are not even built anymore, because it is
possible to just use the object files directly via extract_all_objects().
The occurences of the suffix were detected and removed by performing
a tree-wide search with 'fa' and .fa (note the quotes and dot).
