*printf fix - ' flag

Hash: SHA1
POSIX requires %'d to print a decimal separated by the thousands
separator. Fortunately for newlib, the thousands separator in the C
locale is the empty string. I also discovered that my previous patch to
support %zu and friends was incomplete, since it didn't support %1$zu.

* libc/stdio/vfprintf.c (_vfprintf_r): Support ' flag.
(chclass): ' is a flag. j, t, and z are modifiers.
