7f692409cf [#970] fstree: Handle unsupported O_TMPFILE
Metabase test relied on this behaviour, so fix the test too.

Cherry-picking was hard and did too many conflicts,
here is an original PR:

fc31b9c947 [#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.

da8da1c63a [#98] fstree: Do not fail iteration over just removed files
A directory is read and files are saved to a local variable. The iteration
over such files may lead to a non-existing files reading due to a normal SN
operation cycle and, therefore, may lead to a returning the OS error to a
caller. Skip just removed (or lost) files as the golang std library does in
similar situations:
