Fix printstr's len parameter width

We often pass syscall params and other long-sized values
as printstr(len). Truncating them to int may be a bad thing.

* defs.h: Change len parameter's type from int to long in
string_quote and printstr function declarations.
* util.c (string_quote): Special-case only len==-1, not all len<0.
(printstr): Likewise.
