*/*: Inline mirror://hackage and update URIs

This change inlines mirror://hackage in all ebuilds, and updates URIs
to the modern form (old URIs redirect to that).

The change has been made using the following command:

find -name '*.ebuild' -exec sed -r -i \
  -e 's@mirror://hackage/@https://hackage.haskell.org/@g' \
  -e 's@https://hackage.haskell.org/packages/archive/([^/]*)/([^/]*)/@https://hackage.haskell.org/package/\1-\2/@g' \
  -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{PV}@${P}@g' \
  -e '/hackage\.haskell\.org/s@\$\{MY_PN}-\$\{PV}@${MY_P}@g' \
  -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{MY_PV}@${MY_P}@g' \
  {} +
