IMPALA-5031: link fesupport so FE tests run with UBSAN
This commit enables the frontend and JDBC tests to run under
UBSAN. Before this comit, they fail with an error message about
finding the UBSAN support functions like
__ubsan_handle_load_invalid_value. Linking those functions into
libfesupport.so requires using the linker flag --whole-archive so that
these symbols, which are not directly referenced by the source code
used to build libfesupport.so, are included.
This patch also enables the custom cluster tests to run under UBSAN;
they recently gained frontend tests in commit
d72f3330c1edc9086ba120e6d3469a75c0aea083.

> builds are supported after https://gerrit.cloudera.org/#/c/6186/, but
> Impala's test suite triggers many errors under UBSAN. Those errors should be
> fixed and then there should be a way to run the test suite under UBSAN and
> fail if there were any errors detected.
