Don't use the full file path in the header of the generated config_keys.inc

file, because it leaks actual paths such as /home/rm/svn-1.14.5 into the
tarballs.

Instead, use the same approach already used by write_errno_table(), where the
header reads like "This file was generated by build/generator/gen_base.py".

* build/generator/gen_base.py
  (write_config_keys): Don't use __file__ in the generated header.
