openssh: upgrade 7.8p1 -> 7.8p1+git to support openssl 1.1.x

- Convert from tarball to git repository which support
  openssl 1.1.x

- There is no specific minor version that contains the
  openssl fix (it was merged to master a few days agao),
  rename recipe version to `7.8p1+git'

- Fix regression test binaries missing
  In commit `1f7aaf7 openssh: build regression test binaries', it build
  regression test binaries, since upstream add two binaries in commits
  `c59aca8 Create control sockets in clean temp directories' and
  `1acc058 Disable tests where fs perms are incorrect', we should update
  do_compile_ptest.
