Change the shared bridgetest code from static to dynamic library

...so ASan builds do not complain about ODR violations due to multiple instances
of vtable for testtools::bridgetest::CurrentContextChecker after
a53808c0ed577468393aced90963af6496706959 "loplugin:dllprivate" removed the
SAL_DLLPRIVATE from class CurrentContextChecker (which apparently /did/ have an
impact with -fvisibility-ms-compat, as used by Linux Clang ASan/UBSan builds).
