test: skip sysprof tests with LUAJIT_DISABLE_SYSPROF

LuaJIT has a macro LUAJIT_DISABLE_SYSPROF that disables
sysprof support. Sysprof tests don't respect this macro,
and therefore some of them failed when the macro is enabled.

The proposed patch:

- Skips sysprof testcases in a suite tarantool-c-tests.
- Introduces an environment variable LUAJIT_DISABLE_SYSPROF in
  a suite tarantool-tests that is set to 1 when sysprof support is
  disabled.
- Propagates a status of sysprof support to Lua tests and skip
  testing when sysprof is disabled.
