adb: Link to libdl manually to avoid build failure on android-build

An outdated build environment results in a host adb build failure
because libcrypto needs libdl, but libdl isn't linked explicitly:
out/host/linux-x86/obj/STATIC_LIBRARIES/libcrypto_static_intermediates/libcrypto_static.a(dso_dlfcn.o):
In function `dlfcn_globallookup':
