    libprocstat: make sv_name not static
    
    Making this variable static makes is_elf32_sysctl() and callers thread
    unsafe.
    
    Use a less absurd length for sv_name.  The longest name in the system is
    "FreeBSD ELF64 V2" which tips the scales at 16+1 bytes.  We'll almost
    certainly have other problems if we exceed 32 characters.
