[PATCH] image: Restrict coredumps to *.core files again

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

Looking at every file's mime-type in a rootfs is simply way too costly
and also not needed in practice.

To make my point more concrete. Please speak up if you think that 
coredumps with different endings do play a role. But make sure that case 
is strong:

- 7.5 min. do_rootfs_finalize for meta-iot2050 so far
- 0.5 min. with this change
