updated bitwuzla commit hash / version (#461)

Tested locally, this doesn't segfault when including `bsg_dff.sv` and
other files.

I'm going to keep doing further testing to make sure this change doesn't
break anything.

### What this PR does:
Updates the version of Bitwuzla (SMT solver used by Rosette) to the most
recent version.

### How this PR does it:
In `dependencies.sh`, line 27 defines the Bitwuzla commit hash that's
used by Lakeroad when building everything with Docker.

> `export BITWUZLA_COMMIT_HASH="..."`

I updated the Bitwuzla commit hash to the most recent version, as of
Aug. 21 2024.

### Updates
_Aug 28 2024:_ [An issue in Bitwuzla has been opened that's possibly
related to this](bitwuzla/bitwuzla#121)
