qemu: Add addition environment space to boot loader qemu-system-mips

Browse Source 
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.

qemu: Add addition environment space to boot loader qemu-system-mips
Upstream-Status: Inappropriate - OE uses deep paths
If you create a project with very long directory names like 128 characters
deep and use NFS, the kernel arguments will be truncated. The kernel will
accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
to only 256 bytes. This patch expands the limit.
