Bug 1412427 part 5: Deindent over-indented MPL boilerplate comments down to 1 space, for consistency & alignment. (whitespace-only) r=jrmuizel

This patch was automatically generated. I found the files to be fixed in this
patch with the following command:
grep -r "  \* This Source Code" gfx

...and then I modified each of these files with the following script
(where $1 is the filename to be modified):
###
line1=" \* This Source Code Form is subject to the terms of the Mozilla Public"
line2=" \* License, v\. 2\.0\. If a copy of the MPL was not distributed with this"
line3=" \* file, You can obtain one at http://mozilla\.org/MPL/2\.0/\. \*/"

# Strip off 1 space at beginning:
sed -i s%"^ $line1"%"$line1"% $1
sed -i s%"^ $line2"%"$line2"% $1
sed -i s%"^ $line3"%"$line3"% $1
