Fix: flt.lttng-utils.debug-info: `ip` field is 32bit on 32bit cpus

Issue
=====
The debug-info component enforces that the `ip` field used to resolve
addresses is a 64bit integer, but the LTTng UST `ip` context field is
32bit on a 32bit cpu. A debug-info component thus fail to recognize that
the trace has all the necessary information to resolve the addresses.

Here is the metadata representing the context on a 32bit system:
        event.context := struct {
                integer { size = 32; align = 8; signed = 1; encoding = none; base = 10; } _vpid;
                integer { size = 32; align = 8; signed = 0; encoding = none; base = 16; } _ip;
        };

Here is the metadata representing the context on a 64bit system:
        event.context := struct {
                integer { size = 32; align = 8; signed = 1; encoding = none; base = 10; } _vpid;
                integer { size = 64; align = 8; signed = 0; encoding = none; base = 16; } _ip;
        };

Solution
========
Remove the integer size check in the
`is_event_common_ctx_dbg_info_compatible()` function.

Drawback
========
None.
