Ola x Nilsson fd0980f74f python3-numpy: Use Large File Support version of fallocate
This was supposed to always be the case from upstream but was exposed
by the 64-bit-time QA checker when file function scanning was enabled.

Subject: [PATCH] BUG: Use large file fallocate on 32 bit linux platforms
Using a local prototype for fallocate instead of the fcntl.h header
meant that the redirect triggered by -D_FILE_OFFSET_BITS=64 was not
triggered.
The prototypes in feature_detection_stdio.h should only be used by
functions in setup_common.py. If they are used by the feature
discovery code they might trigger false positives.
