* JIT: use MAP_32BIT on Linux and FreeBSD

Unless RLIMIT_DATA is low enough FreeBSD by default reserves lower 2Gb
for brk(2) style heap, ignoring mmap(2) address hint requested by RPCS3.
Passing MAP_32BIT fixes the following crash

Assertion failed: ((Type == ELF::R_X86_64_32 && (Value <= UINT32_MAX)) || (Type == ELF::R_X86_64_32S && ((int64_t)Value <= INT32_MAX && (int64_t)Value >= INT32_MIN))), function resolveX86_64Relocation, file /usr/ports/devel/llvm40/work/llvm-4.0.1.src/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp, line 287.
