Rollup merge of #140422 - betrusted-io:bump-unwinding-to-0.2.6, r=workingjubilee

unwind: bump `unwinding` dependency to 0.2.6

Xous now fails to compile under nightly, due to the recent change where `#[naked]` must now be wrapped in `unsafe(...)`. The `unwinding` crate was updated to account for this.

With the following `bootstrap.toml`:

```
profile = "library"
change-id = 138934

[build]
build-stage = 2
target = ["riscv32imac-unknown-xous-elf"]

[rust]
std-features = ["panic-unwind"]
download-rustc = false
```

The build fails when trying unwinding v0.2.5:
```
$ ./x.py build
[...]
   Compiling unwinding v0.2.5

```

This patch updates `unwinding` to v0.2.6, which now wraps all issues of `naked` in `unsafe()`.
