Remove wget from the image

wget from busybox doesn't work against bmcweb by default, given that
busybox wget doesn't support TLS.  A quick grep of the codebase shows no
usages of wget except in old skeleton files that nobody appears to use.

Having wget on the bmc confuses engineers, as there's an expectation
that the on-bmc wget should work with bmcweb, when there are concrete
reasons why it doesn't and can't.

Tested: Ran qemu, and verified that wget command now returns not found.
