aglsetup: generate setup manifest file

This patch modifies aglsetup to output the execution context in a
"setup manifest" located in $builddir/aglsetup.manifest

This file can then be processed by another script (distro-manifest-generator.sh)
to generate a complete distro manifest at build time.

Bug-AGL: SPEC-720, SPEC-1741
