ulib: Restrict shared library build to sandbox only

Browse Source 
Shared libraries are only meaningful for sandbox builds that run on the
host system. For bare-metal targets like x86, only the static library
(libu-boot.a) makes sense.

Make CONFIG_ULIB_SHARED_LIB depend on SANDBOX to avoid link errors about
missing C-runtime files.
