setlocalversion: add -e option

Browse Source 
Set the -e option to ensure this script fails on any unexpected errors.

Without this change, the kernel build may continue running with an
incorrect string in include/config/kernel.release.

Currently, try_tag() returns 1 when the expected tag is not found as an
ancestor, but this is a case where the script should continue.
