volser: Rename putshort and putint32

volser: Rename putshort and putint32

dumpstuff.c defines macros for putshort and putint32. However, the
name 'putshort' conflicts with a macro defined on Linux in resolv.h
(which is included by roken.h)

Just rename putshort to afs_putshort and putint32 to afs_putint32 to
solve this problem
