Android build doesn't need deps/regex

deps/regex was included in Android build because Android NDK 4 has
a packaging bug and doesn't have the regular expression functions defined
in its libc.so. The bug has been fixed in subsequent Android NDK releases.

If it is still necessary to work around the bug in Android NDK 4, we
should consider to use an option like ANDROID_NDK_RELEASE or
ANDROID_NDK_RELEASE_NUM.
