kvm tools: don't pass -Wcast-align to the compiler

Browse Source 
GCC 4.7 with -Wcast-align will warn for code like the following:

	bar = (struct foo *)(char *)(0);

which is exactly the sort of code generated by container_of. In
combination with -Werror, this breaks the build.

This patch removes the option from the kvmtool Makefile.
