util.valid_audio validates non-Fortran contiguous arrays

See original GitHub issue

Description

Raised during CR of #960 which cl0sed #959. https://github.com/librosa/librosa/pull/960#issuecomment-521862461

Last time we updated valid_audio was #616 which cl0sed #612

Steps/Code to Reproduce

from librosa import util
import numpy as np

y = np.zeros(1000)
print(util.valid_audio(y))

y_strided = np.zeros(1000)[::2]
print(util.valid_audio(y_strided))

y_clang = np.zeros(1000).reshape(2, 500)
print(util.valid_audio(y_clang, mono=False))

y_fortran = np.asfortranarray(
    np.zeros(1000).reshape(2, 500))
print(util.valid_audio(y_fortran, mono=False))

y_fortran_colon = y_fortran[:]
print(util.valid_audio(y_fortran_colon, mono=False))

Great. Can we roll changes to to_mono into this issue as well?
