perf tools: Add support for PERF_RECORD_KSYMBOL_TYPE_OOL
PERF_RECORD_KSYMBOL_TYPE_OOL marks an executable page. Create a map
backed only by memory, which will be populated as necessary by text poke
events.
Committer notes:
From the patch:
OOL stands for "Out of line" code such as kprobe-replaced instructions
or optimized kprobes or ftrace trampolines.
