[PATCH] pkg-config: allow kernel to be build with esdk

[Saul Wold <sgw@linux.intel.com>]

When the kernel's menuconfig target is called while using the esdk or an
esdk-based container, the pkg-config info that is found is not correct.
The pkg-config info is for the target, but we need the eSDK's information
in order to build the host based menuconfig.

The new pkg-config script checks both that it's in SDK and being called
from the check-lxdialog script in order to limit the scope of when the
pkg-config automagically switches to pkg-config-native.

This script also replaces the default pkg-config-native script.

[YOCTO #11155]
