Subject: [PATCH] auto/os/linux: fix build with libxcrypt

If crypt_r is found in libcrypt, add -lcrypt to CORE_LIBS to avoid the
following build failure with libxcrypt:

objs/ngx_modules.o \
-lpcre -L/home/giuliobenetti/autobuild/run/instance-3/output-1/host/bin/../xtensa-buildroot-linux-uclibc/sysroot/usr/lib -lssl -lcrypto -L/home/giuliobenetti/autobuild/run/instance-3/output-1/host/bin/../xtensa-buildroot-linux-uclibc/sysroot/usr/lib -lxslt -lxml2 -lGeoIP \
-Wl,-E
/home/giuliobenetti/autobuild/run/instance-3/output-1/host/lib/gcc/xtensa-buildroot-linux-uclibc/9.3.0/../../../../xtensa-buildroot-linux-uclibc/bin/ld: objs/src/os/unix/ngx_user.o:/home/giuliobenetti/autobuild/run/instance-3/output-1/build/nginx-1.18.0/src/os/unix/ngx_user.c:18: undefined reference to `crypt_r'
