qemu: Add addition environment space to boot loader qemu-system-mips
The qemu mips malta base board boot loader uses environment strings
with a max length of 256 bytes which is not long enough to accommodate
a long NFS path in addition to the normal kernel boot command line
arguments.
The solution is to expand the environment string length to 1024 bytes.
