Steven Hartland aa9bddf0a8 Fix libsysdecode vmprot flag decoding
Fix the regex used to find vmprot table entries and add the missing include.

This fixes kdumps output of PFLT arguments which would previously look like:
5202 101546 ktrace   PFLT  0x5ae000 0x2<><invalid>2

They now display correctly:
5202 101546 ktrace   PFLT  0x5ac000 0x2<VM_PROT_WRITE>
