[OE-core] [yocto-kernel-tools][PATCH] tools/kconf_check: modify grep pattern

[Hongzhi.Song]

The cmd line, <grep '^[  ]*\(menu\)*config '>, can't
match all expect config options.

This is because that it is not always space after 'config'
in kernel-source/*/.../Kconfig.
e.g. "config  IP_VS_IPV6" in net/netfilter/ipvs/Kconfig

So we should change the cmd to grep '^[  ]*\(menu\)*config\s'.
