configure: fixup bsdsocket detection code for AmigaOS 4.x

The code that detects bsdsocket.library for AmigaOS did not work
for AmigaOS 4.x. This has been fixed and also cleaned up a little
to reduce duplication. Wasn't technically necessary before, but is
required when building with AmiSSL instead of OpenSSL.

Closes #9268
