selftests: core: add tests for CLOSE_RANGE_CLOEXEC
...
check that close_range(initial_fd, last_fd, CLOSE_RANGE_CLOEXEC)
correctly sets the close-on-exec bit for the specified file
descriptors.
Open 100 file descriptors and set the close-on-exec flag for a subset
of them first, then set it for every file descriptor above 2. Make
sure RLIMIT_NOFILE doesn't affect the result.

tests: add close_range() tests
...
This adds basic tests for the new close_range() syscall.
- test that no invalid flags can be passed
- test that a range of file descriptors is correctly closed
- test that a range of file descriptors is correctly closed if there there
are already closed file descriptors in the range
- test that max_fd is correctly capped to the current fdtable maximum
