Link OpenSSL dynamically

[bayandin]

Problem

Statically linked OpenSSL is buggy in multithreaded environment:

• https://github.com/neondatabase/cloud/issues/16155
• Statically compiled pgbench crashes with SSL error: internal error / SIGSEGV / SIGABRT #8275

Summary of changes

• Link OpenSSL dynamically (revert OpenSSL part from [v2] Include openssl and ICU statically linked #8074)

Before:

ldd /usr/local/v17/lib/libpq.so
        linux-vdso.so.1 (0x0000ffffb5ce4000)
        libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffffb5c10000)
        libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffffb5650000)
        /lib/ld-linux-aarch64.so.1 (0x0000ffffb5ca7000)

After:

ldd /usr/local/v17/lib/libpq.so
        linux-vdso.so.1 (0x0000ffffbf3e8000)
        libssl.so.3 => /lib/aarch64-linux-gnu/libssl.so.3 (0x0000ffffbf260000)
        libcrypto.so.3 => /lib/aarch64-linux-gnu/libcrypto.so.3 (0x0000ffffbec00000)
        libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffffbf1c0000)
        libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffffbea50000)
        /lib/ld-linux-aarch64.so.1 (0x0000ffffbf3ab000)
