Auto merge of #61502 - alexcrichton:update-backtrace, r=estebank

std: Update dependency on `backtrace`

Discovered in #61416 an accidental regression in libstd's backtrace
behavior is that it previously attempted to consult libbacktrace and
would then fall back to `dladdr` if libbacktrace didn't report anything.
The `backtrace` crate, however, did not do this, so that's now been
fixed!

Changes: https://github.com/rust-lang/backtrace-rs/compare/0.3.25...0.3.29

Closes #61416
