linux runtime: switch to vmalloc for context[] element allocation

The new eventcount.stp changes can result in relatively large context
structures (33712 bytes each on f19/x86-64), which the stp_kmalloc
widget can sometimes fail to allocate.  Switching to the numa-aware
vmalloc front-end lets these allocations succeed.

TBD: those contexts shouldn't be that large.
