I think that sorts things out. |

Some people try setting RUSTUP_UNPACK_RAM below the minimum RAM needed for a threaded operation. Since, in principle, we need at least IO_CHUNK_SIZE and thus in theory 2x IO_CHUNK_SIZE, this change clamps the unpack RAM between minimum_ram and the computed maximum available RAM.

Some people try setting RUSTUP_UNPACK_RAM below the minimum
RAM needed for a threaded operation. Since, in principle,
we need at least IO_CHUNK_SIZE and thus in theory 2x IO_CHUNK_SIZE,
this change softens the failure mode from a panic to a warning
and then tries anyway. This is likely to succeed and as such
we'll let it happen. The warning should make it clear if there's
a problem, and should not appear for no-sysinfo platforms since
they default to minimum_ram anyway.
