[fedora-arm] polkitd segmentation fault on aarch64

[Radha Mohan]

Hi,
In FC21-aarch64 release the polkitd is causing a segmentation fault on
our arm64 platform (Cavium ThunderX). On debugging we found that the
issue is in the mozjs17-17.0.0-14.fc21 package.

The below patch fixed the issue. The max VA bits on ARM64 is 48.
