Subject: [PATCH] gio: define hasmntopt ourselves under bionic libc

This is a workaround for build conditions one ends up with under termux,
where the defined __ANDROID_API__ level is lower than what is provided
by gcc installed for it, the libc .so nevertheless contains these symbols
thus enabling the codepaths. This definition is only in use when meson
detected the presence of this symbol in the libc.

Fixes #3008
