gnu: erlang: Patch occurrences of /bin/sh in the source.

Previously, the elixir package would often fail to build, as running :os:cmd
would fail, as /bin/sh doesn't exist when building the elixir package. These
changes fix that issue.

* gnu/packages/erlang.scm (erlang)[arguments]: Add new patch-/bin/sh phase to
replace hardcoded references to /bin/sh with a file in the store.
