io_uring: fix breakage in EXPERT menu

Add a dependency for IO_URING for the GCOV_PROFILE_URING symbol.

Without this patch the EXPERT config menu ends with
"Enable IO uring support" and the menu prompts for
GCOV_PROFILE_URING and IO_URING_MOCK_FILE are not subordinate to it.
This causes all of the EXPERT Kconfig options that follow
GCOV_PROFILE_URING to be display in the "upper" menu (General setup),
just following the EXPERT menu.
