[wallet] Consider generated coins mature at COINBASE_MATURITY+1

We're not seeing large reorgs that would justify waiting a large
 amount past the rule required maturity, and the extra three
 hours is just a nuisance. Take one more block to at least give
 the 100th block time to propagate.

Hardcode string in miniupnpcstring.h and remove wine requirement from deps-win32.yml

Credit: sipa, cfields, Luke-Jr and michagogo contributed to this fix.

Removing wine as a win32 build dep is beneficial to fixing Gitian LXC,
which would enable many more people to join in the gitian.sigs process
by being able to build with a linux VM instead of a virt capable host.

Fix and improve release-process.md

This commit adds a step, which is to git checkout the version to be
built. This ensures that the gitian-descriptors for said version will be
the correct ones. In addition, it updates the links for several
dependencies, where the previously existing links were dead.
Switch the order of win32 deps and win32 qt in release-process.md

release-process.md has the deps being built after qt. However, the descriptors for qt call for the deps file.
