[ #970 ] fstree: Add build tag to enable generic version on linux
...
Unless tested, generic version can start gaining bugs. With a separate
build tag we can have the best of both worlds:
1. Use optimized implementation for linux by default.
2. Run tests or benchmarks for both. Note that they are not actually
run automatically now, but this is at leas possible.

[ #970 ] fstree: Move file locking to the generic writer
...
It is not a part of FSTree itself, but rather a way to solve concurrent
counter update on non-linux implementations. New linux implementations
is pretty simple: link fails when the file exists, unlink fails when the
file doesn't exist.

[ #970 ] fstree: Add linux-specific file writer using O_TMPFILE
...
O_TMPFILE is implemented for all modern FSes and it's much easier and safer to
use. If application crashes in the middle of writing this file would be gone
and won't leave any garbage.
Notice that this implementation makes a different choice wrt EEXIST handling,
generic one always overwrites, while this one keeps the old data.
There is no real performance difference.
