[check-config] Search possible files in dir 

If we give a dir as argument for check-config, it will treat the
dir as a config file, and grep config contents from the dir,
and get wrong result, as:
 | # script/check-config.sh /linux
 | info: reading kernel config from /linux ...
 |
 | Generally Necessary:
 | - cgroup hierarchy: properly mounted [/sys/fs/cgroup]
 | - CONFIG_NAMESPACES: missing
 | - CONFIG_NET_NS: missing
 | - CONFIG_PID_NS: missing
 | - CONFIG_IPC_NS: missing
 | - CONFIG_UTS_NS: missing
 | - CONFIG_CGROUPS: missing
 | - CONFIG_CGROUP_CPUACCT: missing
 | - CONFIG_CGROUP_DEVICE: missing
 | - CONFIG_CGROUP_FREEZER: missing
 | - CONFIG_CGROUP_SCHED: missing
 | ...

We can search possible config files in the dir,
after patch:
 | # script/check-config.sh /linux
 | warning: /linux seems not a kernel config, searching other paths for kernel config ...
 | info: reading kernel config from /linux/.config ...
 |
 | Generally Necessary:
 | - cgroup hierarchy: properly mounted [/sys/fs/cgroup]
 | - CONFIG_NAMESPACES: enabled
 | - CONFIG_NET_NS: enabled
 | - CONFIG_PID_NS: enabled
 | - CONFIG_IPC_NS: enabled
 | - CONFIG_UTS_NS: enabled
