[OE-core] [meta-oe][PATCH] gnupg: added a coreutils runtime dependancy to gnupg recipe

[Yahia Farghaly]

From: yahiafarghaly <yahiafarghaly at gmail.com>

When using 'apt-key add' on the target image, the gnupg is required
but for gnupg to be fully functional, the coreutils is required to be exist with the gnupg.
Otherwise, it may throw an error in runtime as one of components of coreutils is missing.
For 'apt-key add', i faced the error of 'comm: command not found' so as proper solution, i submit this change.
