cmake: support local installations of git

From: =?UTF-8?q?Carlo=20Marcelo=20Arenas=20Bel=C3=B3n?= <[email protected]>

At least in systems where the user is local and not an administrator git will install in a subdirectory of %APPDATALOCAL%, so it makes sense to also look there for the shell needed by the cmake integration with Visual Studio.

cmake(windows): fall back to user-wide Git if there is no system Git

On Windows, software is typically either installed into C:\Program Files, where all users can use it, or into a location inside the user's home directory, where only that particular user can use the software.

Git for Windows strongly encourages system-wide installations, but does not prevent user-wide installations.

When building Git via CMake, this matters because we rely on Git for Windows to provide the POSIX shell that is needed to run Git's generator scripts such as generate-cmdlist.sh. So far, we only found Git for Windows if it was installed system-wide, but with this here patch, we also find any user-wide installation.
