tests: update aux

Browse Source 
When we use /dev/loopX device - shift first PV1 sector by 1M
so /dev/loop0 and dm device do not appear as same device.

Also notify lvmetad once 'devs' are created - so in case this
command is called in the middle of test - lvmetad properly
drops its metadata for these devices.

Drop used test.img file between reuse so the 'prepare_vg'
always starts with zeroed disks.

When LVM_TEST_AUX_TRACE is set, allow shell tracing of aux commands.
