[Samba] Samba 4.4.2 "samba-tool ntacl sysvolreset" is not working correctly

[Miguel Medalha]

I don't really know the relevance of this, but I found the following 
typos on three source files related to sysvol.

./examples/misc/adssearch.pl:357:"Default Domain Controllers Policy"    
=> "6AC1786C-016F-11D2-945F-00C04fB984F9",
./libgpo/gpo_util.c:46: "6AC1786C-016F-11D2-945F-00C04fB984F9" },
./python/samba/provision/__init__.py:123:DEFAULT_DC_POLICY_GUID = 
"6AC1786C-016F-11D2-945F-00C04fB984F9"

Note the lowercase "f" in the last numeric group in those three lines. 
Policy IDs normally have uppercase characters.
