indent: Upgrade to 2.2.12

Add two patches to fix the build error.

Add -Wno-error=unused-value for native build
to silence below error:
| In file included from ../../indent-2.2.12/src/indent.h:60:0,
                 from ../../indent-2.2.12/src/indent.c:77:

+Remove regression dir to fix below do_compile
+error:
+| Making all in regression
+| /bin/sh: line 20: cd: regression: No such file or directory
+| Makefile:451: recipe for target 'all-recursive' failed
+
+BTW, it should be safe not to cover regression dir
+as there is no Makefile.in under ${S}/regression
+and the content of ${S}/regression/Makefile as below.
