kconfig: Use config's full path when generating tmp file

If KCONFIG_CONFIG is set to a full path, we should generate the tmp file
in the same directory instead of the current working directory.

BUG=b:112267918
TEST=emerge-grunt coreboot and verified with print statements that the
correct path was used.
