Create win_susp_bcdedit 
This is a more general rule for possible boot/mbr value edits using bcdedit that I have seen in the wild.
It is different than 3288f6425b/rules/windows/malware/win_mal_wannacry.yml
because it is not specific to anyone family (of malware) and also has different CLI options

Rule simplification 
Two selection fields are reduced to one. HKCU and HKLM registry value changes are considered, thus wildcards are added. No change at details.

c73a9e4164 Fix CommandLine in rule sysmon/sysmon_susp_certutil_command 
Below is an example of a test - the command line does not
include the path nor the .exe. I think this comes from the
initial detection on the Image path and the later switch to
command line.

We could also use both the Image path and the Command Line.

Message     : Process Create:
              Image: C:\Windows\SysWOW64\certutil.exe
              CommandLine: certutil  xx -decode xxx
              Hashes: SHA1=8186D64DD28CD63CA883B1D3CE5F07AEABAD67C0
              ParentImage: C:\Windows\System32\cmd.exe
              ParentCommandLine: "C:\Windows\system32\cmd.exe"
