package/libmodsecurity: needs dynamic library

Commit 9fc652a373034118535397fdd4042ab9f8fd7adf was incomplete as
mbedtls can be pulled in libcurl through libssh2 resulting in the
following build failure:

/home/autobuild/autobuild/instance-4/output-1/host/lib/gcc/powerpc64le-buildroot-linux-musl/11.3.0/../../../../powerpc64le-buildroot-linux-musl/bin/ld: /home/autobuild/autobuild/instance-4/output-1/host/powerpc64le-buildroot-linux-musl/sysroot/usr/lib//libmbedcrypto.a(md5.c.o): in function `mbedtls_md5_init':
md5.c:(.text+0x0): multiple definition of `mbedtls_md5_init'; ../../src/.libs/libmodsecurity.a(libmbedtls_la-md5.o):md5.c:(.text+0x0): first defined here
