tdf#151341 Use lzfse compression instead of bzip2
Several users reported that copying the LibreOffice.app package
in the Finder from a .dmg file compressed with lzfse compression
copies the package several times faster than from a .dmg compressed
with bzip2 compression.
On a mid-2015 Intel MacBook Pro running macOS, copying in the Finder
was at least 5 times faster with lzfse than with bzip2. Also, the
hdiutil man page as of macOS Monterey 12.6.2 has marked bzip2 as
deprecated. lzfse is marked as supported since macOS El Capitan 10.11
so this change appears safe.
The one thing that bzip2 has is better compression so a .dmg with
bzip2 should be smaller than with lzfse. A .dmg built from a debug
build was 262M with bzip2 and 273MB for lzfse. So it appears that
lzfse creates .dmg files that are only 4% or 5% larger than bzip2.
