misc: Add support for Linux uio.h RWF_DONTCACHE flag
Linux 6.14 adds the new flag for uncached buffered IO on a filesystem
supporting it.
This caused two test failures as these tests expected the flag
0x00000080 is unused. Add the flag definition to fix these tests on
Linux >= 6.14:
FAIL: misc/tst-preadvwritev2
FAIL: misc/tst-preadvwritev64v2
The test failures were not detected in routine test suite runs because
normally we create the test file in /tmp, where a tmpfs is usually
mounted, and tmpfs does not support this flag. But it can be reproduced
with TMPDIR set to some directory in an ext4 file system.
