Perform host name initialization if computer name can't be read from registry

[Dmitry Timoshkov]

Hello,

due to recent MAX_COMPUTERNAME_LENGTH changes existing Wine/Crossover
installs suffer from old registry keys with computer name being longer
than 15 characters. NtQueryValueKey returns STATUS_BUFFER_OVERFLOW in
that case.

Changelog:
    Dmitry Timoshkov <dmitry at codeweavers.com>
    Perform host name initialization if computer name can't be read
    from registry.
