gnu: ucsim: Update to 0.7.1.

* gnu/packages/embedded.scm (ucsim): Update to 0.7.1.
[source]: Update URI.
[arguments]<#:configure-flags>: Remove as all stable ports are now built by
default.
<#:phases>: Remove obsolete "remove-empty-directory" phase.
[inputs]: Add ncurses, needed for the serialview utility.
[native-inputs]: Add sdcc when needed for tests.
[description]: Update to mention newly supported microcontroller families.
