unit-test: fix undefined struct field SupportVSocks on arm64

Since arch-specific func getExpectedHostDetails holds undefined struct
field SupportVSocks on arm64, unit test TestEnvGetEnvInfoSetsCPUType,
TestEnvGetHostInfo and so on failed.
I'm trying to use generic func genericgetExpectedHostDetails on arm64
to avoid similar issues.

Fixes: #1287
