2lib: Add test_mockable attribute

Some tests mock library functions.  This previously worked due to adding

  CFLAGS += -Xlinker --allow-multiple-definition

to the test binaries.  But the new version of binutils seems to need
the default implementation to be weak if compiled with -O2 in some
cases.  Add test_mockable for use with functions where this is now
needed.

BUG=chromium:723906
BRANCH=none
TEST=Add CFLAGS += -O2 to the makefile, then make -j runtests
     Tests break before this change with -O2, and work afterwards
