Tell nmcli to not escape colon when getting the path of connection profile

Browse Source 
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2151504

When a NetworManager connection profile contains a colon in the name,
"nmcli --get-values UUID,FILENAME" by default would escape the colon
because a colon is also used for separating the values. In this case,
99kdumpbase fails to get the correct connection profile path,
	kdumpctl[5439]: cp: cannot stat '/run/NetworkManager/system-connections/static-52\\\:54\\\:01.nmconnection': No such file or directory
	kdumpctl[5440]: sed: can't read /tmp/1977-DRACUT_KDUMP_NM/ifcfg-static-52-54-01: No such file or directory
	kdumpctl[5449]: dracut-install: ERROR: installing '/tmp/1977-DRACUT_KDUMP_NM/ifcfg-static-52-54-01' to '/etc/NetworkManager/system-connections/ifcfg-static-52-54-01'

As a result, dumping vmcore to a remote nfs would fail.

In our case of getting connection profile path, there is no need to escape the
colon so pass "-escape no" to nmcli,

	[root@localhost ~]# nmcli --get-values UUID,FILENAME c show
	659e09c1-a6bd-3549-9be4-a07a1a9a8ffd:/etc/NetworkManager/system-connections/aa\:bb.nmconnection

	[root@localhost ~]# nmcli -escape no --get-values UUID,FILENAME c show
	659e09c1-a6bd-3549-9be4-a07a1a9a8ffd:/etc/NetworkManager/system-connections/aa:bb.nmconnection
