tdf#119685 Fix infinite loop in gtk3_kde5 filepicker

Since 'string::find()' returns the position of the given
character in the string and that was passed as the amount of
characters to delete from the string, 'm_responseBuffer'
would always be a string starting with a newline character
afterwards, when this part of the code was reached.

Subsequent calls to 'Gtk3KDE5FilePickerIpc::readResponseLine'
therefore always returned an empty string and left
'm_responseBuffer' unchanged, resulting in the lambda function
inside 'readResponse' in 'gtk3_kde5_filepicker_ipc.hxx' to
loop infinitely.

While at it, make a little more explicit that 'it' is of type
'size_t' here.
