tools/nolibc/printf: Simplify __nolibc_printf()
Move the check for the length modifiers into the format processing
between the field width and conversion specifier.
This lets the loop be simplified and a 'fast scan' for a format start
used.
If an error is detected (eg an invalid conversion specifier) then
copy the invalid format to the output buffer.
Reduces code size by about 10% on x86-64.
Some versions of gcc bloat this version by generating a jump table.
All goes away in the later patches.
