[oe] [PATCH] SDK: allow SDK path of various level

[Fabien Proriol]

In the previous version, tar extraction use the --strip-component
option with "4" hard coded value.
If we set another SDKPATH, with a different depth, the sdk installation
fails.

This patch computes the level from the SDKPATH value.
