Create.c: fix uclibc build

Define FALLOC_FL_ZERO_RANGE if needed as FALLOC_FL_ZERO_RANGE is only
defined for aarch64 on uclibc-ng resulting in the following or1k build
failure since commit 577fd10486d8d1472a6b559066f344ac30a3a391:

Create.c: In function 'write_zeroes_fork':
Create.c:155:35: error: 'FALLOC_FL_ZERO_RANGE' undeclared (first use in this function)
  155 |                 if (fallocate(fd, FALLOC_FL_ZERO_RANGE | FALLOC_FL_KEEP_SIZE,
      |                                   ^~~~~~~~~~~~~~~~~~~~
