pkgconfig: allow kernel to be build with esdk

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-esdk 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.

The pkg-config-esdk is only installed as pkg-config inside the eSDK, which
is why we use the sstate post install script and check for if we are in the
esdk environment using the WITHIN_EXT_SDK
