[PATCH 1/2] create-sdpx-2.2.bbclass: Switch from exists to isfile checking debugsrc

[Mark Hatle <mark.hatle@kernel.crashing.org>]

From: Mark Hatle <mark.hatle@amd.com>

While debugsrc is almost always a file (or link), there are apparently
cases where a directory could be returned from the dwarfsrcfiles
processing.  When this happens, the hashing fails and an error results
when building the SPDX documents.
