Subject: [PATCH] fix detection of zstd

This fixes an issue where if the curl lib is not found, then zstd will
not be supported.

The detection method for both curl and zstd uses a shell variable 'error'.
Unless we unset the variable afterward, the results of the curl check
carry over to the zstd check.
