[PATCH] selftests: core: include linux/close_range.h for CLOSE_RANGE_* macros

[Muhammad Usama Anjum]

Correct header file is needed for getting CLOSE_RANGE_* macros.
Previously it was tested with newer glibc which didn't show the need to
include the header which was a mistake.

Fixes: ec54424923cf ("selftests: core: remove duplicate defines")
