[PATCH bpf-next v3 2/2] tools, bpftool: Define attach_type_name array only once

[Tobias Klauser <tklauser@xxxxxxxxxx>]

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

Signed-off-by: Tobias Klauser <tklauser@xxxxxxxxxx>
---
v3: align strings in attach_type_name as suggested by Daniel.
