[OE-core] [PATCH 2/2] package_deb: Use apt-ftparchive

[Ricardo Ribalda Delgado]

Use apt-ftparchive to create a Release file compatible with SecureApt.

apt-ftparchive is not compatible with libpseudo. The calls to ftw()
returns the path in absolute format instead of relative. This produces
wrong Packages and Release files.

ie:
MD5Sum:
d20227a958f6870137ce0e41b7b84307             1453
/home/ricardo/curro/qtec/qt5022/build-qt5022-cesium/build/tmp/deploy/deb/all/Release

This is why it is called with PSEUDO_UNLOAD.

apt-ftparchive is also a more efficient replacement of dpkg-scanpackages:

_64# time PSEUDO_UNLOAD=1 apt-ftparchive packages . >/tmp/kkk

_64# time PSEUDO_UNLOAD=1 dpkg-scanpackages . >/tmp/kkk
dpkg-scanpackages: info: Wrote 6022 entries to output Packages file.
