tdf#127619: external/nss: Load smime3 lib with a path on macOS

A plain dlopen("libsmime3.dylib",...) would search (among other places)
DYLD_FALLBACK_LIBRARY_PATH, which when unset defaults to a set of paths
including /usr/local/lib (so would erroneously find Homebrew's
/usr/local/lib/libsmime3.dylib instead of LO's
LibreOffice.app/Contents/Frameworks/libsmime3.dylib next to the calling
LibreOffice.app/Contents/Frameworks/libnspr4.dylib).

At least macOS 10.15.2 supports a "@loader_path/" prefix in dlopen, to find the
requested library next to the calling code, so use that as a quick fix.  (Should
that turn out to be problematic, there is PORT_LoadLibraryFromOrigin in
workdir/UnpackedTarball/nss/nss/lib/util/secload.c that might be useful in a
more elaborate fix.)
