[TSan] Add tsan-force-options, tsan-runtime-env.
For this moment tsan-runtime-env works without
preloading libtsan, because of huge memory consumption
by libtsan, at least 1:4. So, adding libtsan to ld.so.preload
will require a huge VM space available, because libtsan
has interceptors for allocators as well as libasan.
In this case I see only one way to enable TSan for DSO:
Build an executable with TSan, which requires DSO we want
to execute. In this case compiler will add section .preinit with
TSan initialization and rltd will call this section early than .init
section for other DSO.
