On systems where vmlinux file is not under /usr/lib/debug/lib/modules
directory, 'mod -s|-S' command may fail to find the module's object
file with the below error:
mod: cannot find or load object file for sd_mod module
Fix it by trying all possible module object file extentions while
searching for the object file under /usr/lib/debug/lib/modules
directory.
