Apparently we never updated the x86_64-linux-gnu baseline for gcc-8

seeing errors for the get_entropy symbol added in the previous symbol
version).
The baseline should have been updated after I fixed PR 81092, which
added a new symbol version and exported some new symbols for 32-bit
targets with that version. Because there were no new exports for
x86_64-linux-gnu the baseline file didn't need to be updated. But it
should have been anyway just to add the new GLIBCXX_3.4.24 version
(even though for x86_64-linux-gnu there are no symbols with that
version).
Tested x86_64-linux, committed to gcc-8-branch.
I'll commit the same patch to trunk (which currently has identical
exports to gcc-8-branch).
Here's the equivalent patch for gcc-7-branch.
