mseal sysmap: uprobe mapping

Provide support to mseal the uprobe mapping.

Unlike other system mappings, the uprobe mapping is not established during
program startup.  However, its lifetime is the same as the process's
lifetime.  It could be sealed from creation.

Test was done with perf tool, and observe the uprobe mapping is sealed.
