autotools.bbclass: use relative path to run configure script

The absolute path (/path/to/configure) caused VPATH in Makefile to be an
absolute path, and then it will be in elf files, use relative path to
run configure can fix the problem.

This will reduce 3127 buildpaths QA issues in a world buld (8957 ->
5830).
