ash: consider "local -" case while iterating over local variables in mklocal. 

fixes segfault introduced in 0a0acb55db with functions using "local -".
test-case: f() { local -; local x; }; f

note: with this change applied multiple 'local -'s still cause multiple entries to be added to the localvars list.
this problem will be addressed in a separate commit.
