pal/unsupported: Swap SystemTime::{MIN, MAX}

cvengler · cvengler · commit 348d68443cfa · 2025-11-20T12:59:59.000+01:00
This commit fixes a bug in the pal for unsupported systems with regard
to `SystemTime`, namely that the values of `SystemTime::MIN` and
`SystemTime::MAX` were wrong in the sense that they were swapped, i.e.
the minimum representing the maximum and the maximum representing the
minimum.
