package/graphite2: fix static install

Don't install an incorrect libtool file when building a static library
to fix the following build failure with harfbuzz:

arm-linux-g++.br_real: error: /home/buildroot/autobuild/run/instance-3/output-1/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libgraphite2.so: No such file or directory
make[5]: *** [main] Error 1

+Subject: [PATCH] don't install a libtool file with static library
+
+Static library is supported since version 1.3.11 and
+https://github.com/silnrsi/graphite/commit/2f143c04da5caa43ddf4dba437b2f2bc26bf4238
+
+However, graphite2 is still installing libgraphite2.la which contains
+incorrect information (i.e. dlname set to libgraphite2.so and
+old_library set to ''):
+
+dlname='libgraphite2.so'
+
+library_names='libgraphite2.so.3.2.1 libgraphite2.so.3 libgraphite2.so'
+
+old_library=''
+
+dependency_libs=''
+
+This will result in the following build failure with any applications
+using this file such as harfbuzz:
+
+arm-linux-g++.br_real: error: /home/buildroot/autobuild/run/instance-3/output-1/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libgraphite2.so: No such file or directory
+make[5]: *** [main] Error 1
+
+Instead of trying to fix this libtool file, just disable it when
+building a static library as it is not needed
