package/mokutil: fix dependencies of comment

Since the package was introduced in 2e6e121496bf (package/mokutil: new
package), the dependencies for the comment about missing dependencies
are not all inverted compared to the actual dependencies.

Notably, gcc and headers versions should be negative, not positive,
dependencies. This makes the comment visible even when said dependencies
are met.

Fix that.
