Consider extensions built into the k6 binary when checking if binary provisioning is required

[pablochacin]

The binary provisioning process analyzes the script to be executed to identify the dependencies of extensions. It the current binary does not satisfy them, it will provision a custom binary.

However, this process currently does not consider any extension built into the binary.

For example, if the script requires xk6-faker and the binary already contains this extension, a new binary with the xk6-faker will be provisioned.
