[Tarantool-patches] [PATCH] fiber: fix build for disabled fiber top

[Sergey Kaplun]

In case when we build without `ENABLE_FIBER_TOP` neither
`struct fiber` contains `clock_stat` field nor `FIBER_TIME_RES`
constant is defined.
This patch adds corresponding ifdef directive to avoid compilation
errors.
