[Buildroot] [PATCH 2/3] package/bpftrace: bump to version 0.26.1 to fix build with LLVM 22

[Thomas Perale]

In reply of:
> Since Buildroot commit 25cb3813e7fc6ed3e455f983cf0e09c7bc02fccb which
> bumped LLVM from 21.x to 22.x, the build of bpftrace is broken as
> bpftrace 0.24.2 only supports LLVM up to 21.
> 
> We tried backporting the bpftrace patch that allows using LLVM up to
> version 22 but the patch didn't apply cleanly but more importantly it
> wasn't clear if this patch was sufficient. Therefore, we opt for
> bumping bpftrace entirely to fix the issue.
