devtool: deploy-target: Avoid unnecessary dependency on awk on the target

Browse Source 
Relying on that awk is installed on the target just to extract the
fourth column (i.e., the free volume size) from `df -P` is an
unnecessary dependency for devtool deploy-target. As it is already
using sed to mangle the output from `df -P`, this can easily be
modified to only extract the free volume size.
