package/linuxconsoletools: always select a sub-option

This patch forces BR2_PACKAGE_LINUXCONSOLETOOLS_INPUTATTACH
to be selected if none of the other sub-options are
selected. This fixes build failures when using
'make randpackageconfig', where selecting
BR2_PACKAGE_LINUXCONSOLETOOLS without selecting any sub-option
would break in the 'install to target' phase.

Fixes:

http://autobuild.buildroot.net/results/f62/f62c5e8bd63d21211eb0e658c4e84135bd59b8cb/

And many more.
