Bug#1084190: breakage due to tzdata System V name removal

[Rebecca N. Palmer]

That didn't work because there are 6 places that need to be patched, not 
2.  Working version (in that it passes build+autopkgtest):
https://salsa.debian.org/rnpalmer-guest/glib

I think this means we now have patches for all the known instances of 
this bug, but some of them haven't been accepted yet, and I haven't 
checked recent FTBFS bugs for other affected packages.
