[PATCH v2] btrfs-progs: test: add new test for inspect-internal rootid

["Misono, Tomohiro" <misono.tomohiro@jp.fujitsu.com>]

This new test checks inspect-internal rootid
 - handle path to subvolume/directory/file as an argument
 - get different id for each subvolume
 - get the expected id for each file/directory (i.e. the same as
	 containing subvolume)

Signed-off-by: Tomohiro Misono <misono.tomohiro@jp.fujitsu.com>
---
change log:
v1 -> v2:
  - Moved category from cli-tests to misc-tests
  - When "inspect-internal rootid" fials, echo messages and exit
  (since _fail() is called in subshell, logging is already done)
  - Add quotes to variables
