tracing/uprobe: Fix to make trace_uprobe_filter alignment safe

[ Upstream commit b61387cb732cf283d318b2165c44913525fe545f ]

Commit 99c9a923e97a ("tracing/uprobe: Fix double perf_event
linking on multiprobe uprobe") moved trace_uprobe_filter on
trace_probe_event. However, since it introduced a flexible
data structure with char array and type casting, the
alignment of trace_uprobe_filter can be broken.

This changes the type of the array to trace_uprobe_filter
data strucure to fix it.
