[PATCH v2 7/9] oeqa: support passing custom boot patterns to runqemu

[Enrico Jorns <ejo@pengutronix.de>]

This allows defining non-standard patterns from QEMU tests just as they
are already supported by the testimage.bbclass.

Will allow testing non-Linux shells in QEMU, too, e.g. a U-Boot or other
bootloader shell.
