tests: don't try to mock __open_2 on non-GLibc builds

Mocking of the __open_2 function was added in

    virpcimock: Mock __open_2()

This function only exists in glibc, however, and the mocking code runs
on systems not using glibc, such as FreeBSD. Even Linux hosts might be
using a different libc impl, though we don't actively try to support
that.
