Revert "Fix nan is not a member of std when building android"

This reverts commit cc2bc0bf3cf75307aaa04f4dc8ddce8db678b450.  As discussed at
<https://gerrit.libreoffice.org/#/c/55783/> "Fix nan is not a member of std when
building android":

Stephan: "with exactly what architecture and toolchain did that failure happen;
is this commit still relevant after <https://gerrit.libreoffice.org/plugins/
gitiles/core/+/312eeeee42cb4a1e356943e17305555e41afc4ef%5E!/> 'Switch Android
armeabi-v7a to libc++/libc++abi/libunwind too'?"

Tomaž: "It was a consequence of that limited Bionic libstdc++ that was used in
ANdorid. libc++ should be a modern up-to-date replacements so I guess this
workaraunds are now obsolete and irrelevant."

(And a --with-distro=LibreOfficeAndroid build against NDK r16b indeed succeeded
for me with this revert.)
