[U-Boot] [PATCH] tools: imx8m_image: Fix 'unexpected operator' error

[Carlo Caione]

When sh is an alias for dash the script is failing with (for several
files):

./tools/imx8m_image.sh: 15: [: signed_hdmi_imx8m.bin: unexpected operator

This is caused by the 'a == b' bashism that should be 'a = b'.
