Remove .bss separation

[psjm3]

Current chericat stores the .bss section as a separate entry in the VM table, which is not useful unless it also explicitly store the .data section. However, a discussion with @jrtc27 concluded that it is not useful at all to have explicit entries for either .bss or both of .bss and .data. Therefore to avoid confusion it is best to remove the .bss as separate entry.

Could store the .data section as extra data in the database too, along with .bss, .plt and .got, but more selective when displaying the data on the main vm view and on graphs.
