runtime: use uname version check for 64-bit time on 32-bit arch codepaths

The previous fallback-on-ENOSYS logic causes issues on forks of Linux.

Android: #77621 (CL 750040 added a workaround with a TODO,
this fixes that TODO)
Causes the OS to terminate the program when running on Android
versions <=10 since the seccomp jail does not know about the 64-bit
time syscall and is configured to terminate the program on any
unknown syscall.

Synology's Linux: #77930
On old versions of Synology's Linux they added custom vendor syscalls
without adding a gap in the syscall numbers, that means when we call
the newer Linux syscall which was added later, Synology's Linux
interprets it as a completely different vendor syscall.

Originally by Jorropo in CL 751340.

Fixes #77930
