sci-libs/libgeodecomp: Fix boost detection

When hpx is installed libgeodecomp tries to use the boost libraries detected by
hpx. That doesn't work, because the wrong variables are referenced and hpx uses
fewer boost libraries than libgeodecomp.

So remove that and use the system boost libraries in all cases.

+Subject: [PATCH] cmake: Disable use of HPX boost libraries
+
+First of all the wrong variables are referenced. Second HPX doesn't include
+date_time which is needed by the tracing writer. So that does not work.
+
+Use the system boost libraries.
