tdf#133511 adjust langpack script for removal of CFBundleGetInfoString

3a02841819 removed the string from
Info.plist, but the languagepack install script tried to use that to
make sure whatever the user selects/is found is from the dame type (dev
vs release and codeline/version). Instead of doing multiple
greps/multiline ones (there are multiple version strings in that file,
only one being from LO itself…) use mdls instead to pick the interesting
properties to build a "PRODUCTNAME FULLVERSION" string again we can
match against. --raw switch is nul separated, so add additional xargs -0
in there instead of trying to match a nul with grep
(without --raw it is a nice human readable multiline string)
