meta: toolchain-shar-relocate.sh: Fix for extracting SDK in the same directory as SDK script.

If SDK will be extracted in the same folder as sdk shar script.
The shar_relocate will substitute SDK.sh script SDKPATH with extract destination path.
After that operation no one will be able use this sdk script as paths in it will be different.
To fix this we need to filter out sdk script and relocate_sdk scripts from  SDKPATH substitution
