[OE-core] [PATCHv2] insane.bbclass: avoid false positives on library location

[Bill Randle]

package_qa_check_libdir() reports that the file libsoletta.so.0.0.1-gdb.py
in /usr/share/gdb/auto-load is in the wrong location. Before generating
a warning for files in non-standard locations, check that the file is an
actual elf file (and hence a real library file).
