Bug#967991: glirc, build-depends on package which is not in testing

[peter green]

Package: glirc
Version: 2.35-1
Severity: serious
Justification: rc policy: "packages must be buildable within the same release"

glirc can no longer be built in testing because haskell-regex-tdfa is no longer
present in testing. Ilias Tsitsimpis has filed a bug report against the package
saying he intends to remove it and asked the release team to remove it from
testing ( https://lists.debian.org/debian-haskell/2020/08/msg00002.html ) .
which the release team did.
