package.bbclass: Allow per-package SKIP_FILEDEPS

package.bbclass: Allow per-package SKIP_FILEDEPS

The existing check for SKIP_FILEDEPS can be overridden per recipe
using SKIP_FILEDEPS_pn-${PN}. However, there's no mechanism for
letting a single package within a recipe use SKIP_FILEDEPS.

This patch adds SKIP_FILEDEPS_<pkg>, by analogy to FILES_<pkg>.
Note that it only works one way; if the recipe has SKIP_FILEDEPS = 1,
the checks for individual packages will never be reached.
