sstate: Fix SSTATE_SWSPEC only used by populate_lic tasks
This variable is only used by populate_lic tasks (gcc-source overrides it)
and refers to BPN. In recipes like gcc, where there are multiple variants,
it is resulting in sstate objects which encode PN (they install into a PN subdir)
but the sstate object reflects BPN. This leads to corruption between then and
eventually, warnings from image builds like:
WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc
WARNING: The license listed GPL-3.0-with-GCC-exception was not in the licenses collected for recipe gcc
WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc
WARNING: The license listed NCSA was not in the licenses collected for recipe gcc-sanitizers
WARNING: The license listed MIT was not in the licenses collected for recipe gcc-sanitizers
WARNING: The license listed GPL-3.0-with-GCC-exception was not in the licenses collected for recipe gcc
WARNING: The license listed GPLv3 was not in the licenses collected for recipe gcc
WARNING: The license listed NCSA was not in the licenses collected for recipe gcc-sanitizers
By referring to PN, as used by license.bbclass, this issue is resolved.
