base/license.bbclass: handle multiple INCOMPATIBLE_LICENSEs

Allow INCOMPATIBLE_LICENSE to be a whitespace-separated list of
incompatible license strings and/or glob patterns.

Also fix wildcarding: the string in INCOMPATIBLE_LICENSE was clearly
intended to match with wildcards (e.g. "*GPLv3" to match both GPLv3
and LGPLv3), but this was broken because of a bug in return_spdx()
which would die with a runtime error when there was no SPDXLICENSEMAP
entry for the string.
