[lldb] [unittests] Fix building the FreeBSD arm64 Register Context test

Maybe set it to eRegsetMaskDefault explicitly?

[andrew]

Set opt_regsets to eRegsetMaskDefault

[mgorny]

LGTM now, thanks. I don't have an arm64 cross env handy at the time, so I'm assuming you've tested it.

[andrew]

Yes, I found it by trying to build the tests on FreeBSD/arm64
