Add lvm2 thin provision dump target checker

Browse Source 
We need to check if a directory or a device is lvm2 thinp target.

First, we use get_block_dump_target() to convert dump path into
block device, then we check if the device is lvm2 thinp target by
cmd lvs.

is_lvm2_thinp_device is now located in kdump-lib-initramfs.sh, for it
will be used in 2nd kernel. is_lvm2_thinp_dump_target is located in
kdump-lib.sh, for it is only used in 1st kernel, and it has dependencies
which exist in kdump-lib.sh.
