fbdump: only build VGA16 support on x86/x86-64

The VGA16 dumping feature probably doesn't make much sense on anything else than x86 and x86-64, as it is accessing I/O ports that seem PC-specific.

Moreover, some architectures such as SH4, do not have an implementation of outw() in uClibc, but we quite certainly don't care about VGA16 support for such architectures.

Fixes:
