c5c1d19ebb loader: Only extend segments if kernel supports page size migration 
It has been found that some existing apps have implicit dependencies on
the address ranges in /proc/*/maps. Since segment extension changes the
range of the LOAD segment VMAs some of these apps crash, either by
SIGBUS or in yet unidentified ways.

Only perform the segment extension optimization if the kernel has the
necessary mitigations to ensure app compatibility.
