That's your kernel version string that got into the kernel at its
compile time.  It won't be changing when you switch the "personality"
for a program or for an entire container to 32-bit, and that's OK.
Your kernel is clearly capable of running both 64- and 32-bit programs
(in other words, it's been compiled with 32-bit syscall emulation
support).  The "amd64" in the version string should not concern you.
It's just a string.  It could as well say "zilog80" or whatever if the
person compiling the kernel wanted so, which would not affect the
kernel's operation in any way.
