dev-scheme/guile-zstd: depend on zstd moved to /lib

Without the dependency there is a chance that on upgrade
dev-scheme/guile-zstd will be updated first and be built against zstd in
/usr/lib.

dev-scheme/guile-zstd: unbreak libzstd.so.1 loading

::gentoo's commit 1ae31721a "app-arch/zstd: add split-usr support"
broke dynamic loading of `libzstd.so.1` because now pkg-config path
does not match directory where ELF shared library resides. As a result
guix fails to load it as:

$ guix environment re2c --check
...
substitute: ice-9/boot-9.scm:1685:16: In procedure raise-exception:
substitute: In procedure load-foreign-library: file: "/usr/lib64/libzstd.so.1",
message: "file not found"

The change hardcodes /lib/ path to a real library.
