ci: forward GGSQL_SKIP_GENERATE into manylinux Docker container (#167)

The Linux aarch64 manylinux build runs inside Docker, so environment
variables from the workflow aren't automatically available. Pass
GGSQL_SKIP_GENERATE=1 via docker-options so the build script uses
pre-generated parser files instead of trying to regenerate them.
