package_manager/oe-pkgdata-util: fix complementary package installation

We currently have a problem regarding complementary package installation,
that is, if 'oe-pkgdata-util glob' maps out packages that are not in
the oe-rootfs-repo, we will get error like below:

  No match for argument: lib32-glibc-locale-en-gb
  Error: Unable to find a match: lib32-glibc-locale-en-gb

Here are the steps to reproduce the issue:
1. Add the following lines to local.conf:
   require conf/multilib.conf
   MULTILIBS ?= "multilib:lib32"
   DEFAULTTUNE:virtclass-multilib-lib32 ?= "core2-32"
   IMAGE_INSTALL:append = " lib32-sysstat"
2. bitbake lib32-glibc-locale && bitbake core-image-full-cmdline

This problem appears because:
1) At do_rootfs time, we first contruct a repo with a filtering
   mechanism to ensure we don't pull in unneeded packages.[1]
2) oe-pkgdata-util uses the pkgdata without filtering.

In order to avoid any hardcoding that might grow in the future[2], we need
to give 'oe-pkgdata-util glob' some filtering ability.

So this patch does the following things:
1) Add a new option, '-a/--allpkgs', to 'oe-pkgdata-util glob'.
   This gives it a filtering mechanism. As it's an option, people who use
   'oe-pkgdata-util glob' command could use it as before.
2) Add to package_manager 'list_all' function implementations which
   list all available functions in our filtered repo.
