gdbhooks.py: dump-fn, dot-fn: cast ret values of fopen/fclose
Work around the following
(gdb) Python Exception <class 'gdb.error'> 'fclose@@GLIBC_2.2.5' has
unknown return type; cast the call to its declared return type:
(gdb) Error occurred in Python: 'fclose@@GLIBC_2.2.5' has unknown
return type; cast the call to its declared return type
This is due to GDB not being able to pick up and use the return types from
debug info for external declarations.

* gdbhooks.py (DumpFn.invoke): Add explicit casts of return values of
fopen and fclose to their respective types.
(DotFn.invoke): Ditto.
