config/APM: Add option to disable building of APM support on Linux 

APM support in the Xserver was used to restore the console mode
    prior to a power management event. This was to ensure the mode
    upon suspend/resume was one that the system firmware or kernel
    could deal with.
    APM support is now largely obsolete, KMS drivers don't require a
    mode restoration anyhow. Therefore it should be possible to disable
    this feature.

(small modification by keithp - move test for XF86PM flag after check
for APM, then move XF86PM flag to xorg-config.h.in)
