[PATCH v1 2/9] tools/x86/kcpuid: Properly align long-description columns

[Ahmed S. Darwish]

When kcpuid is invoked with "--all --details", the detailed description
column is not properly aligned for all bitfield rows:

CPUID_0x4_ECX[0x0]:
	 cache_level        	: 0x1       	- Cache Level ...
	 cache_self_init     - Cache Self Initialization

This is due to differences in output handling between boolean single-bit
"bitflags" and multi-bit bitfields.  For the former, the bitfield's value
is not outputted as it is implied to be true by just outputting the
bitflag's name in its respective line.

If long descriptions were requested through the --all parameter, properly
align the bitflag's description columns through extra tabs.  With that,
the sample output above becomes:

CPUID_0x4_ECX[0x0]:
	 cache_level        	: 0x1       	- Cache Level ...
	 cache_self_init     			- Cache Self Initialization
