imxtract: specify max gunzip size

Browse source 
Specify max gunzip size from config to override SYS_XIMG_LEN
default value wich is 0x800000. In case we have a large portion of FIT
image, for example gzipped kernel with decompressed size large than
0x800000 we should enlarge imxract area, otherwise extracting it will
fail.

It used to be a hardcoded define in cmd/ximg.c and we are moving it to
config.

This provides the size of the commad-line argument area
used by imxtract for extracting pieces of FIT image.
It should be large enough to fit uncompressed size of
