Subject: [PATCH] Don't set shell explicitly for the build steps

Bash is used by default under all platforms we're going to support here,
so there is no need to specify it explicitly. Moreover, by default the
appropriate shell options (such as "pipefail", as well as "e") are used,
and there is no need to override them.
