base-files: fix sysupgrade 'wget' handling for uclient-fetch

change 48451 tried to add support for uclient-fetch by moving
/usr/bin/wget to /bin/wget, but this change kept the symbolic
link to /bin/busybox as install_bin creates links to param 1

the desired fix is to link to uclient-fetch to wget:
  install_bin /bin/uclient-fetch /bin/wget
