Merge #18437: util: Detect posix_fallocate() instead of assuming
182dbdf0f4b6e6484b0d4588aaefacc75862a99c util: Detect posix_fallocate() instead of assuming (Vasil Dimov)
Pull request description:
Don't assume that `posix_fallocate()` is available on Linux and not
available on other operating systems. At least FreeBSD has it and we
are not using it.
Properly check whether `posix_fallocate()` is present and use it if it
is.
