[fedora-arm] Fedora 27 Anaconda systemd fail, /dev/disk/ by-path enumeration name does not match CentOS/RHEL 7.3, 7.4, 7.5

Description of problem: in RHEL 7.3, 7.4, and 7.5-SNAP1 using the following Beaker Kickstart Metadata

ignoredisk=--only-use=/dev/disk/by-path/platform-APMC0D33:01-ata-1.0 "clearpart=--initlabel --all" zerombr

On Fedora 27, anaconda fails with the following message:

An error occurred during reading the kickstart file: The following problem occurred on line 32 of the kickstart file:
Disk "/dev/disk/by-path/platform-APMC0D33:01-ata-1.0" given in ignoredisk command does not exist.
The installer will now terminate. Pane is dead

Issue: In RHEL 7.3/7.4/7.5 & CentOS 7.3/7.4, in /dev/disk/by-path/...
the path name "platform-APMC0D33:01-ata-1.0" has decimal extension i.e. "1.0"

In Fedora 27, in /dev/disk/by-path/...
the path name "platform-APMC0D33:01-ata-1" has no decimal extension i.e. "1"

When using disk specific targeting for OS install on systems with more than 1 installable device, this inconsistency causes issues with automation and common kickstart
