AP_Filesystem: Better estimation of filesize for parameter file

Browse Source 
The actual filesize of the parameter downloadfile is around
15200 bytes. The indicated filesize is used in QGC for the
progressbar. This patch does not try to compute the exact filesize
but I try a better estimate. Only the full download off all
parameters is considered to avoid more complexity.
