cam: Allow specifying directories in the --file option

The value of the --file option is the full name of the file to which
captured frames are written. To write files to a specific directory with
the default naming scheme, the "frame-#.bin" name has to appear at the
end of the file name. Simplify usage of the option by allowing --file to
specify a directory only. If the file name ends with a '/', the default
"frame-#.bin" file name is automatically appended.
