fix(native-comp): fix re-linking and signing issue with *.eln files

With the recent move of shared libraries and native lisp *.eln files to
Contents/Frameworks, the re-linking paths became longer, causing code
signing to fail with headerpad errors. This change ensures there's
enough space within binary files for longer shared library relink paths,
and code signing payloads.
