build: cleanup configure script PKG_CHECK_MODULES

Cleanup the configure script package include lines.  There isn't a set
style for this yet, but this is an attempt to improve readability
whereas it's often one long line per library.  The CI will fail if there
aren't backslashes on lines for the AC_CHECK_HEADER.
