Change `GetDeviceLocal` device selection

For `GetDeviceLocal` only consider a device if the full path to the device
matches the first part of the path to match.

The issue was that putting in a file that was not in a sub-path of an existing
mounted device failed. So if the rpcs3 devices are in
D:\DEV\rpcs3\bin and you open D:\DEV\ps3autotests\tests\rsx\primitives\primitives.ppu.elf
it would return
/dev_usb000/ps3autotests\tests\rsx\primitives\primitives.ppu.elf
which resolves to
D:/DEV/rpcs3/bin/dev_usb000/ps3autotests/tests/rsx/primitives/primitives.ppu.elf
and is wrong.

Correct are either /dev_usb000/../../../ps3autotests\tests\rsx\primitives\primitives.ppu.elf
or /hostfs/D:\DEV\ps3autotests\tests\rsx\primitives\primitives.ppu.elf

I chose to resolve without the ".." beyond root, since that just seems wrong
(so it will now return the hostfs version).

Fixes #1090
