Carlos Venegas 6491b9d7aa qemu: Add support to build static qemu for dev tree
Update static build scripts to allow build qemu dev tree.
When qemu starts the process for a new version the patch number
from the qemu version is more than 50. Add logic to detect it
and not apply patches fro the base branch.

For example:

Qemu 5.2.50 means the beginning for 6.0 development. After detect a
development version, patches for 5.2.x will not be applied.
