[Libguestfs] [PATCH 2/2] sparsify: handle output filenames with ':'

[Pino Toscano]

With commit a594b7f90a682e2a9327b142138edb76ad8ba8ff the checks for
input and output files with ':' were removed; while the input file is
handled correctly by the disk_create API, an output filename with ':'
could still be handled as specifying a transport, failing the last
"qemu-img convert" call.

Use the new qemu_input_filename helper to handle the output filename
correctly.
