scripts/functions: do not abort on failed svn

In case of eglibc, some add-ons that were previously external are
now internal (bundled with the main sources).

So we do not want to fail if an add-on can't be downloaded; we
want to post-pone the check until we can extract the main archive.

So:
 - try to retrieve the add-on
 - if it fails, print a warning instead of calling CT_Abort
 - return 1

So, components that want to catch the error and want to handle it can,
while components that do not will gracefuly fail thanks to our catching
every errors.

Bonus: it works without changing any existing retrieval procedure! :-)
