libstd: Use CLOCK_BOOTTIME for Instant

maurer · maurer · commit 98caf8b3836c · 2021-11-10T19:11:30.000Z
Discussion is ongoing upstream at rust-lang/rust#87906 about how exactly to make a change like this, but most of the concerns (backwards compatibility, legacy kernels prior to 2.6.39, non-Linux OSes) are not applicable to us. If upstream decides to keep `Instant` as `CLOCK_MONOTONIC`, we should figure out an alternate solution for our use of `quiche` before backing this out.
