dumpstate: Fix required dependencies

TARGET module dumpstate requires non-existent: df
TARGET module dumpstate requires non-existent: getprop
TARGET module dumpstate requires non-existent: ip6tables
TARGET module dumpstate requires non-existent: kill
TARGET module dumpstate requires non-existent: lsmod
TARGET module dumpstate requires non-existent: lsof
TARGET module dumpstate requires non-existent: netstat
TARGET module dumpstate requires non-existent: printenv
TARGET module dumpstate requires non-existent: top
TARGET module dumpstate requires non-existent: uptime
TARGET module dumpstate requires non-existent: vril-dump

df, kill, lsmod, lsof, netstat, printenv, top, uptime are symlinks of toybox.
getprop is symlink of toolbox.
ip6tables is symlink of iptables.
vril-dump doesn't exist.
