oeqa/utils/qemurunner: Add support for Unicode from qemu
The current state of qemurunner will drop the Unicode
characters received from qemu, this is because error
report web had problems with Unicode characters; now
that the server support Unicode, it is possible to
log all the output from qemu. So far the only Unicode
character seen is the copyright symbol.
This patch allows to get Unicode characters from the qemu
target and save the log in an UTF-8 file for latter use.
