ci: Update the CI scripts
Implement the following updates:
* Add CI_SYSNAME and set it to `uname -s`.
* Set the default CI_CC value to "clang" on all BSD systems.
* Replace CI_SRCDIR_REL_BUILDDIR and CI_INSTALLDIR_REL_BUILDDIR
with CI_SRCDIR_NATIVE and CI_INSTALLDIR_NATIVE.
The former variables were hard-coded and error-prone; the new
variables are computed and safe to use.
