lib/vsprintf.c: fix handling of %zd when using ssize_t
Documentation/printk-formats.txt says to use %zd for a ssize_t argument
and some drivers do. Unfortunately this prints a positive number for
negative values eg:
tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error 4294967234
Add a case to va_args a ssize_t type if the interpretation should be
signed.
Tested on PPC32.
