Bagas Sanjaya f73dffae4f package/git: fix wchar-less uclibc build 
The package fails to build on wchar-less uClibc-ng configuration
(i.e. without BR2_TOOLCHAIN_BUILDROOT_WCHAR selected):

make[1]: *** [Makefile:2795: t/unit-tests/clar/clar.o] Error 1
```

This is because since version 2.47.0, Git imports clar unit testing
framework, which uses wchar_t. On wchar-less uClibc-ng configuration,
however, the installed <wchar.h> header is a stub (that is, wchar_t
is undefined).

Apply upstream patchset from Patrick Steinhardt [1], which includes
upstreamed clar build fix.
