cmd/pxe.c: Rework initrd and bootargs handling slightly

For the initrd portion of handling our bootm arguments we do not have a
sufficiently long enough buffer for some improbable 64bit cases.  Expand
this buffer to allow for a 64bit address and almost 256MB initrd to be
used.  Make use of strncpy/strncat when constructing the values here
since we know what the worst case valid values are, length wise.

Similarly for bootargs themselves, we need to make use of strlen/sizeof
and strncpy/strncat to ensure that we don't overflow bootargs itself.
