Sergei Golubchik 7b527e6334 cmake: fix krb5 detection on SUSE
`zypper install krb5-devel` installs executables outside of $PATH.
It also installs /etc/profile.d/krb5.sh that is sourced by a new
shell to add the new location to the $PATH. But this doesn't affect
the current shell.

Now decent Linux distros remind the user to run `. /etc/profile`
to reload paths in such a case. SUSE doesn't and for a good reason -
it doesn't work there. Because SUSE sets PROFILEREAD=true in the
environment and /etc/profile does not do anything.

By this point, one should not really expect `unset PROFILEREAD` to help,
and it does not - PROFILEREAD is readonly, and cannot be unset.

Apparently SUSE really *really* wants you to re-login between installing
MariaDB build dependencies and actually running the rpmbuild.

Which we cannot do it buildbot. And it would look very user-un-friendly
in the Build Instructions section of the manual.

So, we work around it - by adding SUSE krb5 path to the search list.

THIS IS SUSEEEEEE!!!
