packages: make bhyve depend on acpi

[novel]

Summary

bhyve(8) needs iasl(8) to run, otherwise it fails with:

/bin/sh: /usr/sbin/iasl: not found
bhyve: BASL failed @ build_dsdt:484
    Failed to execute basl_compile(ctx, basl_fwrite_dsdt): Unknown
error: 32512
bhyve: BASL failed @ acpi_build:899
    Failed to execute build_dsdt(ctx): Unknown error: 32512
Assertion failed: (error == 0), function bhyve_init_platform_late, file
/home/pkgbuild/worktrees/main/usr.sbin/bhyve/amd64/bhyverun_machdep.c,
line 394.

Register the "acpi" package, which provides iasl(8), as a dependency for
bhyve.

This is only a dependency on amd64, arm64 and riscv don't need this. But, I don't know if there's a way to express that.

it will be possible to express this after D56087 lands. currently, it's not, UCL can't be conditional.

uh... sorry, i didn't mean to remove markj! i'm not sure how that happened.

I wasn't able to find a way to express that either, but as the acpi tools are available on arm64 (didn't check riscv), my though was it's better to pull extra (unnecessary) dependency on arm64 than crashing like that on amd64.
The approach in D56087 should allow to solve it better indeed.
