Subject: [PATCH] default-crate-overrides: add zstd-sys and fuser

zstd-sys: set ZSTD_SYS_USE_PKG_CONFIG so build.rs probes the system
libzstd via pkg-config instead of compiling the vendored C amalgamation
from scratch in every consumer.

fuser: with the default-on libfuse feature, build.rs discovers libfuse
via pkg-config and has no vendored fallback, so it fails in the sandbox
without pkg-config and fuse3 in scope.
