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 Change-Id: I1f9bc8a6d8bc4c659e59ed0025f71ad9e1c86355 Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh>
