checklayer: parse LAYERDEPENDS with bb.utils.explode_dep_versions2()

LAYERDEPENDS is a string of this format:
"DEPEND1 (optional version) DEPEND2 (optional version) ..."

However when we parse LAYERDEPENDS in _get_layer_collections() we
parse it as a simple string, and if any optional versions are there the
'depends' field is wrong. For example, running yocto-check-layer
might result in such errors:

ERROR: Layer meta-python depends on (>= and isn't found.
ERROR: Layer meta-python depends on 12) and isn't found.

Let's use bb.utils.explode_dep_versions2() to parse LAYERDEPENDS, and
create a string that contains all dependencies, effectively
skipping/ignoring any optional versions.
