[Buildroot] [PATCH] fs/common.mk: Strip extra whitespace when device table is empty

Since ROOTFS_DEVICE_TABLES it is a concatenation of two strings
separated by spaces, there will always be a space on it, which means
it's never empty. Therefore, when testing for empty, the condition
never evaluate to false.

The following change fixes this problem; it runs the qstrip on
the overall combination of the variables, causing the space to be
removed if it's the only thing left.
