[PATCH] support: Enhance support/tst-support_descriptors compatibility

[Florian Weimer]

Some container environments have different devices for /dev and
/dev/null, leading to extra error output on the second line:

error: descriptor 3 changed from "/dev/null" to "/dev"
error: descriptor 3 changed device from 0:5 to 0:49
error: descriptor 3 changed ino from 4 to 1

The expected error matcher did not capture this before.
Technically, the inode number can remain unchanged due to the
changed device ID, so simply drop that check.
