assemble_vintf: accept arch specific kernel fragments

It is now allowed to provide the following arg:
--kernel=3.18:.../android-base.cfg:.../android-base-arm64.cfg

assemble_vintf detects the name of these files and
sets conditions accordingly. For example,

* android-base.cfg refer to common configs (no conditions)
* android-base-foo-bar.cfg refer to configs that are
  conditioned on CONFIG_FOO_BAR being set.

Also, android-base.cfg must exist for each version.

Test: m system_compatibility_matrix.xml -j
