bugfix: segfault due to invalid dynafile cache handling

Browse Source 
Accidently, the old-style cache size parameter was used when the
dynafile cache was created in a RainerScript action. If the old-style
size was lower than the one actually set, this lead to misadressing
when the size was overrun, and that could lead to all kinds of
"interesting things", often in segfaults.
