py3-gitlab: add py3-requests-toolbelt dependency

py3-gitlab: upgrade to 2.7.1

py3-gitlab: bump pkgrel

py3-gitlab: re-introduce package

This package was removed for being "upstream" in Alpine, but it does not
actually appear to be.

todo.sr.ht: remove pystache dependency

builds.sr.ht: fix use of $subpkgdir

py3-humanize: upgrade to 3.5.0

py3-sshpubkeys: upgrade to 3.3.1

This should allow for FIDO/U2F ssh keys of various types.

Also, it seems there was a typo in the dependencies referencing
py3-crypto when py3-cryptography is what is needed[1].
