Fix: liblttng-ust-tracepoint missing symbols when using ld "no-undefined"

When using the LDFLAGS="-Wl,-no-undefined", ld complains about undefined
references to ust_safe_snprintf, patient_write and init_usterr.
The fix is to add the appropriate libraries where those symbols
are defined to the libtool LIBADD flag.
