adding ubuntu support, fixing fedora linux config

Review Ubuntu with Firemarshal/Firesim

[abejgonzalez]

Also @ffard-lbl had some issues building w.r.t to hanging in QEMU?

[ffard-lbl]

@abejgonzalez That's correct. There's two issues that I noticed when building:

• When I run ./marshal -v build ubuntu-base.json, the build hangs near the end of the build. The disk image is still created, but it doesn't finish running the build process. Attached is the end of the log from the build:

• When you launch the ubuntu-base.json image and log in as ubuntu:ubuntu, the console asks for a new password as the original ubuntu password is set to expire at login. This also may be the reason the build halted during the build, as it was asking for an updated password.
