package/zstd: drop useless check-package disable
Commit 52154e52069d (package/zstd: build multithreaded library if
supported) added an override of a previously defined variable, so an
explicit check-package exception was added in 0f0e913f10ca
(package/zstd: rework build and install). Eventually, in 253a951c4fe7
(package/zstd: fix build without threads) the variable override was
removed.
However, the check-package exception was left out during the rework in
253a951c4fe7, so it now excludes nothing.
Drop this exception now.
