[PATCH 2/2] license.bbclass: Bound beginline and endline in copy_license_files()

[Peter Kjellerstedt <pkj@axis.com>]

Ensure that begin_idx (i.e., beginline - 1) and end_idx (i.e.,
endline) are positive numbers in copy_license_files(). This makes sure
the same lines are copied as populate_lic_qa_checksum() uses when it
calculates the checksum. Before, beginline=0 would typically lead to
that no lines were copied at all.
