[Buildroot] [git commit] dependencies: check for extract tools as well

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=2c6390a5d0c01420879e9f23bc89afb19976da4a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Most of the extract tools (gzip/bzip/..) we already check for explicitly
in dependencies.sh (as they are used outside GENTARGETS), but not for
xzcat.
The .xz format is used fairly rarely, and it is likely to not be available
on build hosts, so an explicit (hardcoded) check for it isn't optimal.
Instead, add the inflate tools used to DL_TOOLS_DEPENDENCIES, similar to
how we do it for svn/git/bzr/...
