build: provide LUAJIT_USE_PERFTOOLS option

This patch provides the LUAJIT_USE_PERFTOOLS flag via the CMake build
system. It allows avoiding the definition of the cognominal macro
definition via CMAKE_C_FLAGS to use integration with the Linux perf
tools interface [1] to resolve symbols for traces generated by a JIT.

It may be used like the following:

| perf script record luajit test.lua
| perf report -s symbol
