[PATCH] virt-aa-helper: fix clang build

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

Clang complains about wrong argument type:

libvirt/src/security/virt-aa-helper.c:174:11: error: absolute value
      function 'abs' given an argument of type 'long' but has parameter
      of type 'int' which may cause truncation of value [-Werror,-Wabsolute-value]
    idx = abs(pos - orig);
          ^
