Include support for translating 32-bit auxv vectors on non-64-bit
platforms that aren't riscv (which has no 32-bit ABI support and

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.

libprocstat: simplify auxv value conversion
Avoid a weird dance through the union and treat all 32-bit values as
unsigned integers. This avoids sign extension of flags and userspace
pointers.

procstat_getfiles_sysctl: do not require non-null ki_fd
ki_fd is legitimately NULL when 32bit process requests process data
from 64bit host kernel. The field is not used by the code for sysctl
case; procstat_getfiles_kvm() checks ki_fd.
