[0.21] depends: update Qt 5.9 source url

[kwvg]

Expected Behavior

Running make in the depends directory should result in the successful building of host platform dependencies

Actual Behavior

make terminates as qt.mk points to (now) outdated URL path for Qt 5.9 sources, returning error 404

Remedy

Update qt.mk to point to updated source location as Qt has relocated them

[hebasto]

Since #21376 we are using Qt 5.12.10.

[kwvg]

Having depends of still officially supported versions point to dead URLs doesn't seem the most advisable, a lot of projects rely on those supported versions being functional in a complete sense

Ah, this change into 0.21 branch.

ACK deff4e7, I have verified the new link, and checked that old one is unavailable:

curl: (22) The requested URL returned error: 404 Not Found

Btw, make should use https://bitcoincore.org/depends-sources in such cases.

Should LTS be bumped to 5.9.9?

on branch 0.21, performing a depends build, fetching from the current URL will fail and we default to the bitcoincore.org backup:

Fetching qtbase-opensource-src-5.9.8.tar.xz from https://download.qt.io/official_releases/qt/5.9/5.9.8/submodules

curl: (22) The requested URL returned error: 404 Not Found
Fetching qtbase-opensource-src-5.9.8.tar.xz from https://bitcoincore.org/depends-sources

With this PR cherry-picked on top of the 0.21 branch, we can successfully download qt 5.9.8 and not have to rely on the backup:

Fetching qtbase-opensource-src-5.9.8.tar.xz from https://download.qt.io/archive/qt/5.9/5.9.8/submodules```
