perf inject: Fix processing of ID index for injected instruction tracing

The ID index event is used when decoding, but can result in the
following error:

 $ perf record --aux-sample -e '{intel_pt//,branch-misses}:u' ls
 $ perf inject -i perf.data -o perf.data.inj --itrace=be
 $ perf script -i perf.data.inj
 0x1020 [0x410]: failed to process type: 69 [No such file or directory]

Fix by having 'perf inject' drop the ID index event.

Fixes: c0a6de06 ("perf record: Add support for AUX area sampling")
