Drop support for /etc/opt/ure and ~/.ure from LibreOffice 4

For one, /etc/opt/ure was probably never used by anyone anyway, so meant just
needless file-stats during startup.  For another, accidentally created
~/.ure/javasettings_*.xml that later became stale were noted to cause trouble,
so that source is now closed.

For this to work, jvmfwk needs to be silent now if it cannot read/write any
shared/user javasettings_*.xml.
