drop unneeded indirect openssl dependency

Since adding the rlua dependency I can no longer execute gitpad built on
my developer machine on my server, since it fails with:

  gitpad2: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by gitpad2)

As it turns out an easy workaround is to statically link MUSL
(by passing --target x86_64-unknown-linux-musl to cargo build).

The openssl-sys dependency (pulled in by git2) however failed to build
for MUSL. Since we don't need it the simplest solution is to just drop it.
