Set some GC parameters only for dalvik 

Commit https://github.com/CyanogenMod/android_frameworks_base/commit/8f566390bceee9f01b1721c4d00b1b246d26be16


fixed parsing of certain GC values. Before the result was "" and so the
if statement was always false, never executing the setTargetHeap* calls.

Now they are executed but ART currently doesn't support setting
heapminfree and heapconcurrentstart resulting in a UnsatisfiedLinkError
Exception.

Check for the used runtime first and only execute the methods for Dalvik.
