erlang: fix non-hipe builds

Restore some PLIST content state from prior to the 23.2.4 update,
which mistakenly moved some hipe-related files that get built
universally to the PLIST.hipe list. The "--disable-hipe" option does
not impact everything. Build tested with the hipe option both enabled
and disabled. This should fix build breakages, e.g., NetBSD/aarch64.

(Separately, it's kind of unfortunate that this package uses both PLIST
variables and separate PLIST files to segment content driven by options.
It should really use one approach or the other consistently, but I
haven't touched that here.)
