btrfs-progs: split global help HELPINFO_INSERT_GLOBALS

Browse Source 
As of now the define HELPINFO_INSERT_GLOBALS if used as in the example
as below (as of now its not been used anywhere) will print the help
texts as shown below

$ ./btrfs fi show --help

 <snip>

    Global options:
    --format TYPE      where TYPE is: text

So in preparation to add --verbose and --quiet global options, and
apparently --format is not being used yet, this patch splits the global
options into two defines.

                                       "Global options:"

So that the currently added global options --verbose and --quiet can use
the define HELPINFO_INSERT_GLOBALS header as shown below.

$ ./btrfs fi show --help
<snip>

    Global options:
