meta-intel: Fix layer priority

After adding the rsyslog bbappend some changes were not applied
because the meta-phosphor layer also has an rsyslog bbappend at
a higher priority.

This change makes meta-intel depend on meta-phosphor so that
recipes here are treated with a higher priority.

Tested:
rsyslog.conf override from meta-intel is applied.
