[Buildroot] [git commit] package/zstd: rework build and install

[Arnout Vandecappelle (Essensium/Mind)]

commit: https://git.buildroot.net/buildroot/commit/?id=0f0e913f10caf21f23c2e46f210519a7a3bc0b32
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Create libzstd.pc in the build step instead of triggering a
lazy build during installation when it is missing.

Move PREFIX=/usr to ZSTD_OPTS. It is needed for building libzstd.pc
during the build step; for consistency, make sure it's available in all
steps.

Attach '-release' to the targets, since the default is to
build lib-release and zstd-release. Its only effect is to clear
DEBUGFLAGS (which are just warning flags).
