patch against glib20 in ports.

Hi,

while trying to understand why the performance of xfce4 (especially
xfce4-appfinder) was poor on my system I discovered the same bug as the
reporter of thuis bug. I created the attached patch to test whether I could get
any significant performance gains by using the sysctl api to enumerate file
descriptors. 

Before patch:
  - start time of xfce4-appfinder >3s.

After patch:
  - start time of xfce4-appfinder <1s (instant).
