tests: Update x86 boot tests to use x86-ubuntu-img
The x86-boot-exit resource is being deprecated for the more versatile
x86-ubuntu-img resource. The latter attempts to run `m5 readfile`,
allowing a user to specify a script to be run. If no script is specified
`m5 exit` is run. Therefore it can be used in the x86-boot-exit tests.
