[Buildroot] [PATCH] lttng-tools: disable on uClibc

lttng-tools has been broken on uClibc since a long time due to dlmopen()
and LM_ID_BASE not being implemented. The issue has been reported to the
upstream lttng developers more than two months ago [1], and no fix has
been provided. Therefore, it's time to disable it on uClibc.

Fixes:
