gskit: Fix errors from Curl_strerror refactor

2f0bb864c1 replaced sterror with Curl_strerror, but the strerror buffer
shadows the set_buffer "buffer" parameter. To keep consistency with the
other functions that use Curl_strerror, rename the parameter.

In addition, strerror.h is needed for the definition of STRERROR_LEN.

Closes #8454
