* add failing test case to highlight the race condition on bug
note : the test "TestLock" is non deterministic, its outcome depends
on the sequence of instructions yielded by the go scheduler on each run.
There are two values, "goroutines" and "succesfulLockCount", which can
be edited to see how the test performs.
With the committed value, resp "20" and "50", I had a 100% failure on
my local machine, running linux (Ubuntu 20.04).
Sample test output :
$ go test . -run TestLock
--- FAIL: TestLock (0.17s)

* flock: create a wrapper module, local to bitcask, around gofrs.Flock
the racy TestLock has been moved to bitcask/flock
* flock: add test for expected regular locking behavior
* flock: replace gofrs/flock with local implementation
* update go.sum
* Add build constraint for flock_unix.go
