bionic: test: report kernel sha for clock_getcpuclockid failure 

For aarch64 only.

Once we activate support for vdso call for clock_getres, we also will
have to deal with kernel bugs in the implementation. If the kernel is
prior to the vdso unification of arm, aarch64 and aarch32, estimated
to land in 4.15, then the assembler implementation for aarch64 will
need two upstream kernel fixes e1b6b6ce and c80ed088. We report the
required url for the upstream kernel fixes upon test failure.

Test: bionic-unit-tests --gtest_filter=time.*
