lscpu: cure empty output of lscpu -b/-p

lscpu: cure empty output of lscpu -b/-p

On riscv, /proc/cpuinfo looks like:

	processor       : 3
	hart            : 4
	isa             : rv64imafdc_zicntr_zicsr_zifencei_zihpm_zba_zbb
	mmu             : sv39
	uarch           : sifive,u74-mc
	mvendorid       : 0x489
	marchid         : 0x8000000000000007
	mimpid          : 0x4210427
	hart isa        : rv64imafdc_zicntr_zicsr_zifencei_zihpm_zba_zbb

As none of the cputype_patterns match any of the fields in that file,
`cpu->type` is never set, which causes `get_cell_data` to always
return nullptr. The output of `lscpu -b --extended=CPU` and `lscpu
-p` is then empty.

Resolve that.
