[yocto] [meta-selinux][PATCH] conf/layer.conf: use BBFILES_DYNAMIC for dynamic layers

[Yi Zhao]

From: Robert Yang <liezhi.yang at windriver.com>

The previous code add all BBFILE_COLLECTIONS/recipes*/*/*.bbappend to BBFILES,
which causes the parsing very slow when there are many layers, e.g., I have 87
layers:

* Before:
$ rm -fr tmp-glibc/ cache; time bitbake -p
real    0m45.173s
user    0m0.560s
sys     0m0.060s

* After:
$ rm -fr tmp-glibc/ cache; time bitbake -p
real    0m25.542s
user    0m0.572s
sys     0m0.040s

It wasted 20s which wasn't worth (The host has 128 threads, it should cost more
time on less power host), use BBFILES_DYNAMIC can fix the problem.
