tests: dbus update

Always use  PREFIX for vg header - all tests must use this prefix,
VGs without are not allowed.

Modify pv_symlink test - as the test was checking unsupportable
combination - since lvm2 commands withing testsuite are only
allowed to manipulate with /dev/mapper/LVMTESTXXXX path -
nothing else allowed and fails on being filtered.
