[xslt] Build error on Solaris w/o snprintf

["Nick Deubert" <ndeubert gmail com>]

Hello,
Recently I tried to build libxslt on Solaris (SunOS 5.5.1) and got the
following warning and link error. I made the change below (not sure if
it's even ok to do this) and it seemed to fix it for me.
Thanks,
Nick
