test-container: Use xcopy_file_range for cross-device copy [BZ #23597]
copy_file_range can't be used to copy a file from glibc source directory
to glibc build directory since they may be on different filesystems.
This patch adds xcopy_file_range for cross-device copy.

[BZ #23597]
* support/Makefile (libsupport-routines): Add
support_copy_file_range and xcopy_file_range.
* support/support.h: Include <sys/types.h>.
(support_copy_file_range): New prototype.
* support/support_copy_file_range.c: New file. Copied and
modified from io/copy_file_range-compat.c.
* support/test-container.c (copy_one_file): Call xcopy_file_rang
instead of copy_file_range.
* support/xcopy_file_range.c: New file.
* support/xunistd.h (xcopy_file_range): New prototype.
