libsass: fix runtime version

The version.h should be generated from version.h.in. But there is
already a version.h file in source directory. When ${S} != ${B}, the
version.h is generated in build directory, and the original version.h in
source directory is not overwritten. However, the latter is used during
the build, resulting in a missing runtime version. Remove version.h from
source directory to ensure that the one in build directory is used
during the build.

Before the fix:
$ sassc --version
sassc: [NA]
libsass: [NA]
sass2scss: 1.1.1
sass: 3.5

After the fix:
$ sassc  --version
sassc: 3.6.2
libsass: 3.6.6
sass2scss: 1.1.1
sass: 3.5

+Subject: [PATCH] Remove version.h from source directory
+
+The version.h should be generated from version.h.in. If the build
+directory is out of the source directory, the version.h is generated in
+build directory and the original version.h in source directory is not
+overwritten. However, the latter is used during the build, resulting in
+a missing runtime version:
+
+$ sassc --version
+sassc: [NA]
+libsass: [NA]
+sass2scss: 1.1.1
+sass: 3.5
+
+Remove version.h from source directory to ensure that the version.h in
+build directory is used during the build.
+
+Also remove '--dirty' option from 'git describe' command line in
+version.sh to get rid of '-dirty' suffix from version number that
+was introduced with this change.
