meson: fix condition for io_uring stubs

CONFIG_LINUX_IO_URING is not included in config-host.mak and therefore is
not usable in "when" clauses.  Check the availability of the library,
which matches the condition for the non-stubbed version block/io_uring.c.

At this point, the difference between libraries that have config-host.mak
entries and those that do not is quite confusing.  The remaining ~dozen
should be converted in 6.2.
