package/spirv-tools: needs dynamic library

Fix the following static build failure raised since the addition of the
package in commit 0a01085abeb7d8a097cb68b9f7f4faec7711543c:

[ 26%] Linking CXX shared library libSPIRV-Tools-shared.so
/home/autobuild/autobuild/instance-11/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/12.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: /home/autobuild/autobuild/instance-11/output-1/host/xtensa-buildroot-linux-uclibc/sysroot/usr/lib/libc.a(__uClibc_main.os): in function `__uClibc_init':
__uClibc_main.c:(.text+0x98): undefined reference to `__fini_array_start'
