Robert Yang c5ffdcbe37 runqemu-gen-tapdevs: Allow run --help without sudo
Then we can get user's UID and GID rather than hardcode to 1000, e.g.:

- Without sudo
$ runqemu-gen-tapdevs --help
[snip]
$ sudo ../poky/scripts/runqemu-gen-tapdevs 15220 100 4 tmp/sysroots-components/x86_64/qemu-helper-native/usr/bin
[snip]

- With sudo
$ sudo ../poky/scripts/runqemu-gen-tapdevs --help
[snip]
$ sudo ../poky/scripts/runqemu-gen-tapdevs 15220 100 4 tmp/sysroots-components/x86_64/qemu-helper-native/usr/bin
[snip]

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
