Update PatchCheck to not enforce no tabs and not enforce CR/LF
line endings for .gitmodules files. These files are updated by
git when a git submodule command is used and the updates by git
use tab characters and LF line endings.
Also update patch check to not enforce CR/LF line endings for
patch lines that create a submodule directory. These patch
lines use LF line endings. The git submodule directory is
added as a new file with attributes 160000 that can be detected
by looking for the pattern "new file mode 160000".
