JIT: fix building with ENABLE_JIT on OpenBSD targets (#2398)

Browse Source 
* sockaddr_in is a forward declaration on *BSD, explicitly include the correct header

* fix building with ENABLE_JIT on OpenBSD targets

* add wxallowed linker flag for openbsd targets

* OpenBSD armjit sc_exr -> sc_elr

* wxallowed -> wxneeded

* force mmap for jit on OpenBSD

* disable fastmem on OpenBSD

* fix typo in disabling fastmem for OpenBSD

* add missing space in this if
