tools: rework tools-core dependecies

ZSTD and libdeflate do not depend on SED nor flock, so instead of the whole
for loop that will filter 2 out of 4 core packages just specify that patch
and tar depend on sed explicitly.

ZSTD now depends on libdeflate since libdeflate-gzip will then be used to
unpack ZSTD as well as most tool archives.
