tools/nolibc/printf: Change variables 'c' to 'ch' and 'tmpbuf[]' to 'outbuf[]'

Changing 'c' makes the code slightly easier to read because the variable
stands out from the single character literals (especially 'c').

Change tmpbuf[] to outbuf[] because 'out' points into it.

The following patches pretty much rewrite the function so the
churn is limited.
