[Buildroot] [git commit] core/apply-patches: store full path of applied patches

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=a3165461bb0af6b3fdea436efeb7207779aa8f20
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Currently, we only store the filename of the applied patches.

However, we are soon to want to install those patches in the legal-info
directory, so we'll have to know where those patches come from.

Instead of duplicating the logic to find the patches (bundled,
downloaded, from a global patch dir...), just store the full path to
each of those patches so we can retrieve them more easily later on.

Also always create the list-file, even if empty, so that we need not
test for its existence before reading it.
