Revert "Cherry-pick systemd mangle-escape patch"

This reverts commit 8ef5fd21107625d7480346318cb858759e61ee66.

The pull request referenced in the original commit was never merged
into systemd.

Support for properly using /sys/devices paths as template instances
has been added to systemd in the meantime.

It probably didn't/doesn't make sense to use device tree paths when
launching applications via udev+system (applications to use
/sys/devices paths instead).

Given all these reasons, drop these two systemd patches.

(From meta-phosphor rev: ee22593ddc009cda7aad28bf1311f1a26047fc97)
