fsl-dynamic-packagearch: add all possible MACHINE_SOCARCH feeds to PACKAGE_EXTRA_ARCHS
This ensures that all possible MACHINE_SOCARCH feeds are part of PACKAGE_EXTRA_ARCHS.
For ARM, dependent on the instruction set we can have two MACHINE_SOCARCHs
e.g. armv7ahf-vfp-neon-mx6qdl armv7at2hf-vfp-neon-mx6qdl
so we must put both into PACKAGE_EXTRA_ARCHS. Otherwise a image recipe will
only find packages from one of the two PACKAGE_EXTRA_ARCHS.
