Subject: bitbake: lib/bb/utils: add safeguard against recursively deleting
 things we shouldn't

Add some very basic safeguard against recursively deleting paths such
as / and /home in the event of bugs or user mistakes.

Addresses [YOCTO #7620].

(Bitbake master rev: 56cddeb9e1e4d249f84ccd6ef65db245636e38ea)
