[Buildroot] [PATCH 1/1] package/tor: fix static build

[Bernd Kuhls]

A static build fails at configure

checking for SSL_SESSION_get_master_key... no

This activates code incompatible with libopenssl in tortls_internal.h
which leads to a build error:

In file included from src/lib/tls/tortls_openssl.c:61:0:
./src/lib/tls/tortls_internal.h:48:8: error: conflicting types for
 'SSL_SESSION_get_master_key'
 size_t SSL_SESSION_get_master_key(struct ssl_session_st *s,

The configure check fails because libz is not used for linking:

/data/buildroot/buildroot-test/instance-0/output/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libcrypto.a(c_zlib.o): In function `zlib_stateful_expand_block':
c_zlib.c:(.text+0x40): undefined reference to `inflate'

This patch add -lz when needed and fixes
