Hi Kai,
In your layer, create a .bbappend matching the basename of the package
you want to change. Using your example, create
recipes-connectivity/openssh/openssh_6.6p1.bbappend (make sure
versions match).
Then you can either replace or patch ssh_config. I would patch it.
Create your patch, put it in recipes-connectivity/openssh/files, and
name your patch file, ending in .patch in SRC_URI in your .bbappend
file.
Your .bbappend file might look something like this:
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI += "file://myssh_config.patch"
The first line instructs bitbake where to search for your patch file.
The second line will cause the file to be fetched into your ${WORKDIR}
for openssh, and because it has a .patch extension, it will
automatically be applied.
The excellent Yocto Project Developer Manual has an example of a
.bbappend file, although its slightly outdated. You no longer need PR
field, and SRC_URI should be += instead of "=".

Yocto Project is gifted with some of the best documentation in the
open source world.
Good luck!
