Per discussion of #2513, Ubuntu Core was going to use UEFI removable path as default esp path, and it needs to change some parts around getting the esp path and searching the shim app path. Also, a new option "FallbacktoRemovablePath" is added into uefi.conf to be applied in this case, and it will be false by default.
