gx: update go-log

[djdv]

We still have components that use the old log though:

updating go-log to version 1.4.1 (QmTG23dvpBCBjqQwyDxV8CQT6jmS4PSftNr1VqHhE3MLy7)
dep go-libp2p-secio also imports go-log (QmRb5jh8z2E8hMGN2tkvs1yHynUanqnZ3UeKwgN1i9P1F8) (1.4.0)
dep go-libp2p/go-tcp-transport/go-reuseport also imports go-log (QmSpJByNKFX1sCsHBEp3R73FL4NF6FnQTEGyNAXHm2GS52) (1.2.0)

These need updating as well for
#2124 and #3068 to be fully resolved.

This is going to have to wait for a libp2p update. Having different versions of the log package at different points in the tree is no bueno

@djdv can you go through the tree and make sure the subpackages (in libp2p) all have go-log updated correctly? that libp2p update i mentioned is getting ready to happen, and it would be great for this all to go through at the same time

The go-log update was included in #5007. go-log is now consistently 1.4.1 (QmTG23dvpBCBjqQwyDxV8CQT6jmS4PSftNr1VqHhE3MLy7)
