Jagadeesh Krishnanjanappa 8b1bc367be runqemu: fix MACHINE being detected as qemuarm for qemuarm64 kernel image
Basically, runqemu script autodetects MACHINE type based on the
kernel image name; if MACHINE name is not specified. Since 'qemuarm'
string is common in both qemuarm amnd qemuarm64 kernel image names, the
MACHINE type is considered as 'qemuarm' even when qemuarm64 kernel
image name is given in command line.
