teach mklog to look in the current directory for ChangeLog files

 when run in repos other than gcc mklog fails to find ChangeLog files
because it looks for $0/../$dir/ChangeLog, but of course if the diff is
for a project other than gcc that might not exist.  It should be fine to
also look for $cwd/$dir/ChangeLog, and use that if we find it.  This
means that for example in binutils-gdb.git you can do git commit,
and then in your editor read git diff HEAD~ | mklog - to generate a
template ChangeLog for that commit.
