run/image/uboot: use gzip --fast by default

Browse Source 
By making the use of gzip's '--best' option configurable and disabling it
by default, this patch noticably reduces the built-test cycle from 15 to
10 seconds when integrating the Sculpt system image for the PinePhone.

Fixes #4693

# Make gzip compression more aggressive

# Using this option reduces the image size by circa 10%. But it comes at the
# cost of significantly slowing down the gzip step for large images (e.g., 6
# seconds instead of 2 seconds for a image of 13 MiB). The option is suitable
# when building a release. But for quick build-test cycles, it is best keep
# it disabled.
