[Tarantool-patches] [PATCH luajit 07/19] build: fix non-Linux/macOS builds

[Sergey Kaplun]

This patch is a follow-up for the commit
a170eb8be9475295f4f67a086e25ed665b95c8ea ("core: separate the profiling
timer from lj_profile"). It moves the timer machinery to the separate
module. Unfortunately, the `profile_{un}lock()` calls for Windows and
PS3 wasn't updated to access `lj_profile_timer` structure instead of
`ProfileState`.

Also, it is a follow-up to the commit
f8fa8f4bbd103ab07697487ca5cab08d57cdebf5 ("memprof: add profile common
section"). Since this commit the system-dependent header <unistd.h> and
`write()`, `open()`, `close()` functions are used. They are undefining
on Windows, so this leads to error during the build.

This patch fixes the aforementioned misbehaviour. After it our fork may
be built on Windows at least.
