[PATCH] util/cutils: Skip "." when looking for next directory component

[Stefan Weil]

When looking for the next directory component, a "." component is now skipped.

This fixes the path(s) used for firmware lookup for the prefix == bindir case
which is standard for QEMU on Windows and where the internally
used bindir value ends with "/.".

This patch is required for Windows to get the firmware access right,
but would also be needed for Linux with --bindir=/usr/local which
currently results in a search path like /usr/local/../share/qemu-firmware.

I noticed that qemu-firmware is not used during the installation.
What is the purpose of that extra search path?
