kbuild: fix call to adjust_autoksyms.sh when output directory specified

When a different output directory is specified during the build process (with
O= or KBUILD_OUTPUT), the call to adjust_autoksyms.sh script fails with the
following error:
/bin/sh scripts/adjust_autoksyms.sh \
  "make KBUILD_MODULES=1 -f ../Makefile autoksyms_recursive"
  /bin/sh: scripts/adjust_autoksyms.sh: No such file or directory
  make[2]: *** [vmlinux] Error 127
  make[1]: *** [sub-make] Error 2
  make: *** [__sub-make] Error 2

Using the absolute path with $(srctree) variable solves the problem.

This is in case the CONFIG_TRIM_UNUSED_KSYMS option is specified.
