[PATCH xserver] configure: use backticks rather than $() for commands

[Gaetan Nadon]

Using git send-email, the CC to "Keith Packard <keithp at keithp.com>" did
not work. I used the same command to send a patch to the list and CC
Alan and it did work. Maybe someone had this problem before.

I am resending the patch that has been reviewed, with the review tags.
