ѕ3:buildsystem: fix depenencies for libreplace
This problem became visible after adding the picky -z defs linker option: On
Solaris libreplace had unresolved symbols, which showed up in the libtalloc
build. PAM_WINBIND_EXTRA_LIBS and WINBIND_NSS_EXTRA_LIBS had been workarounds
to make things work at two placeѕ. These variables have been obsoleted now.
This patch introduces LIBREPLACE_LIBS which contans the linker flags needed for
linking anything using libreplace.
