Do not make io_select return errors on unsupported READ/WRITE mode
The descriptor is valid, it is just the mode which is not available.
* console-client/kbd-repeat.c (repeater_select): Drop SELECT_URG flag from
`type'. Return 0 instead of EINVAL if `type' contains SELECT_WRITE.
* console-client/pc-mouse (repeater_select): Likewise.
* trans/mtab.c (trivfs_S_io_select): Return 0 instead of EBADF when the
openmodes do not match the requested modes in `type'.
* trans/new-fifo.c (io_select_common): Likewise.
* trans/fifo.c (io_select_common): Likewise.
* trans/null.c (trivfs_S_io_select): Likewise.
* trans/streamio.c (io_select_common): Likewise.
