elfutils: Fix size passed to snprintf for invalid sh_name case
Following build error will appear on Fedora18.
nm.c: In function 'show_symbols_sysv':
nm.c:756:27: error: argument to 'sizeof' in 'snprintf' call is the same expression as the destination; did you mean to provide an explicit length? [-Werror=sizeof-pointer-memaccess]
snprintf (name, sizeof name, "[invalid sh_name %#" PRIx32 "]",
