Work around emscripten bugs and missing features in absl/time:time_test.

The emscripten toolchain has a couple of issues that cause time_test
to fail. Specifically:

1) emscripten doesn't support signals.
2) The javascript implementation of strftime/strptime use different expansions
of '%c' that mean it doesn't round-trip.

Replace calls to getpagesize() with the more portable sysconf(_SC_PAGESIZE); the latter is in POSIX 1.0 and is called out in the Linux `getpagesize` man page as a more portable spelling.
