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

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.
