kernel/yocto: fix search for defconfig from src_uri

Fetcher provides full paths to defconfig and scc files, which awk
comparison operator does not catch during construction of
src_uri_defconfig and sccs_from_src_uri lists. This causes the
src_uri_defconfig variable to come out empty, and fails further
validation if defconfig is only supplied via SRC_URI.

Replace comparison operator with awk match function which searches for
sub-string during filtering, effectively placing defconfig from SRC_URI
into src_uri_defconfig and scc files in sccs_from_src_uri respectively.

Fixes: 23dcff0d396c (kernel/yocto: ensure that defconfigs are processed first)
