ubifs-utils: Add spinlock implementations
Add spinlock implementations, because there are some spinlocks
(eg. c->cnt_lock, c->buds_lock) used in UBIFS linux kernel libs.
The spinlock is implemented based on pthread mutex.
This is a preparation for replacing implementation of UBIFS utils with
linux kernel libs.
