license.bbclass: Introduce AVAILABLE_LICENSES that lists all licenses

Previously, there was SRC_DISTRIBUTE_LICENSES, an undocumented
variable that contained a static list of licenses. It was used by
expand_wildcard_licenses() to expand any wildcards used in, e.g.,
INCOMPATIBLE_LICENSE. However, since this static list of licenses has
not been kept up-to-date, many licenses were missing, with the result
that if one tried to use any of those licenses with a wildcard, no
licenses would be found, effectively ignoring that they should be
marked as incompatible.

This introduces a new (documented) variable, AVAILABLE_LICENSES, that
is automatically updated to contain all licenses found in any
directories specified by ${COMMON_LICENSE_DIR} and ${LICENSE_PATH},
and uses it instead of SRC_DISTRIBUTE_LICENSES when expanding
wildcards.
