c97a31b47b mdbx: fix inappropriate/irrelevant MDBX_WANNA_RECOVERY when the DB size is not rounded to sys-allocation-granularity (imported from the stable branch). 
For now this is just the patch that eliminates regression by making the
least risky/invasive changes. However a complete fix involves refining
the rounding of a database size, which still is to do.

The check corrected by this commit was never fundamentally important,
but it was added to verify the logic of rounding the database size in
various cases.
However, after the commit `2a7f460345edbeb26a51782cbe6af3c55254ae77`
(using `fallocate()` to prevent `SIGBUS`), the behavior change led to
the returning error `MDBX_WANNA_RECOVERY` in fairly harmless conditions.

2a7f460345 mdbx: fix unexpected SIGBUS is not enough space in a filesystem. 
On a modern Linux the allocation of space for a file can be deferred
and/or lazy, rather than when setting its length using `ftruncate()`.
The actual allocation of space occurs when writing to the corresponding
areas of the file, or when reading ones (in this case, the file system
fills these areas with zeros).

The specific behavior depends on the type of file system and the kernel
version, but the main thing is that possibilities currently are, when
setting the file size, just the instantaneous ability to allocate space
is checked, without any booking.

If the file system is running out of space, an `ENOSPC` error may occur
when processing (inside a OS kernel) a page fault when accessing one of
the added pages after the database has been enlarged. In this case, the
OS kernel has no other alternative but to send a `SIGBUS` signal to the
process.

This commit fixes the problem by adding the use of system calls to
explicitly allocate space for a given file size.
Related-to https://github.com/erigontech/erigon/issues/16709

This is a simple improvement, however which is complicated by the need
to take into account the availability of the appropriate system API and
handle non-fatal errors from file systems that do not support the
appropriate operations. Therefore, there is a risk of regressions in
unusual/rare situations, including when hosting databases on network
media.
