[LTP] [PATCH v2 1/1] tst_kvcmp: Strip double quotes when parsing /etc/os-release

[Petr Vorel <pvorel@suse.cz>]

ID is normally without double quotes, e.g.: ID=debian

But at least SLES and openSUSE contain double quotes, e.g.:
ID="opensuse-tumbleweed"

thus optionally strip the double quotes after scanning them.

Fixes: e2e60a39b ("lib/tst_kvercmp: Add support /etc/os-release")
