bug#44827: tests/channels.scm: Test failures building on Debian i386 or armhf with libgit2-dev 1.0.1

[Vagrant Cascadian]

Fun With More Debian packaging test suite failures...

Updating the build dependency to libgit2-dev >= 1.0.1 (which pulls in a
similar version to what guix is using) fixes test suite failures ... but
only on the amd64 architecture. The same tests pass Using an older
version of libgit2-dev (0.28). FWIW, this is building with guile-3.0.

The newer version of libgit2-dev introduces several test suite failures
on i386 (and armhf) architectures, but the tests work fine on
amd64. from tests/channels.log on i386:
