[linux-yocto][PATCH] ver_linux: Use /usr/bin/awk instead of /bin/awk

Most Linux distributions contain awk in /usr/bin by default, not in /bin. This
script's suggested use is for creating version information for bug reporting.

Without this patch, Poky's kernel-devsrc package fails to install correctly
because the runtime dependency of /bin/awk is not found.  This package contains
all the source and scripts including ver_linux.
