[zbin] Fix compilation warnings for util/zbin.c

Recent gcc versions generate warnings when compiling util/zbin.c
( tested with gcc-4.3.3 ):

util/zbin.c: In function ‘process_zinfo_pack’:
util/zbin.c:200: warning: format ‘%#zx’ expects type ‘size_t’, but argument 6
has type ‘long unsigned int’
util/zbin.c: In function ‘process_zinfo_add’:
util/zbin.c:257: warning: format ‘%#lx’ expects type ‘long unsigned int’, but
argument 4 has type ‘int’
util/zbin.c:266: warning: format ‘%#lx’ expects type ‘long unsigned int’, but
argument 4 has type ‘int’
util/zbin.c:266: warning: format ‘%d’ expects type ‘int’, but argument 8 has
type ‘long unsigned int’
util/zbin.c:286: warning: format ‘%#lx’ expects type ‘long unsigned int’, but
argument 6 has type ‘int’
util/zbin.c:286: warning: format ‘%#lx’ expects type ‘long unsigned int’, but
argument 7 has type ‘size_t’

This patch eliminates these warnings.

Tested with gcc-4.3.3 on Ubuntu 9.04 and gcc-4.1.2 on Debian Etch.
