bundles/left4me: spread HARDENING_SERVER into left4me-server@.service

Browse source 
Replaces the inline hardening directives on the gameserver unit with
the shared HARDENING_SERVER dict. Removes legacy ReadOnlyPaths /
ReadWritePaths (superseded by TemporaryFileSystem + BindReadOnlyPaths
+ BindPaths in the dict). Brings the unit to the proven Test 7
composition with the i386 amendment (SystemCallArchitectures=native x86)
and PrivatePIDs=true.

Not deployed until bw apply.
