tools, bpftool: Define attach_type_name array only once

Browse source 
Define attach_type_name in common.c instead of main.h so it is only
defined once. This leads to a slight decrease in the binary size of
bpftool.

Before:

   text	   data	    bss	    dec	    hex	filename
 399024	  11168	1573160	1983352	 1e4378	bpftool

After:

   text	   data	    bss	    dec	    hex	filename
 398256	  10880	1573160	1982296	 1e3f58	bpftool
