[PATCH v2] python3-numpy: Use Large File Support version of fallocate

[PATCH v2] python3-numpy: Use Large File Support version of fallocate

[Ola x Nilsson]

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.
+
+Upstream-Status: Backport [https://github.com/numpy/numpy/commit/f49c6f9ea735cd7f718e74f8d637ffbbd3a7a03b]
