sandbox: Allow "clock_gettime64" syscall where defined

Browse Source 
On 32-bit architectures where Linux provides the "clock_gettime64" system call,
including i386, glibc uses it in place of "clock_gettime".  Modify the sandbox
implementation to match, to prevent Tor's monotonic-time functions (in
src/lib/time/compat_time.c) failing when the sandbox is active.
