Make alpm_graph state signedness explicit

The signedness of char is implementation defined. Since the
alpm_graph state is clearly meant to be signed, make the
signedness explicit.

This fixes bugs on systems where char is unsigned, in comparissons
of the following type:

  if(v.state == -1)

which, if state is unsigned, will never be true due to integer
promotion rules.

Fixes failing test/pacman/tests/sync012.py when compiling with -funsigned-char.

Fixes two warnings [-Wtype-limits] for comparissons with -1 when compiling
with -funsigned-char.
