git: Remove redundant ** in these .gitignore files

As such use of **/ versus no prefix lends the same effect per [1] below.

Fix sorting while editing these, based on the documented LC_COLLATE=C.

Ignore temporary build artifacts during maven builds

Add .polyglot.build.properties and .tycho-consumer-pom.xml to .gitignore
because they are temporary build artifacts and are not meant to be under
source control.

ftrace: fix trace entry size computation when header len is 0

In a trace.dat files, trace entries have a 32 bit header that contains
the payload len (in 32 bit words) in the lower 5 bits.

A len of 0 is a special case: the actual entry length is in the next
32 bit word, and that length includes the length field itself, so:

- the event data starts after the length fields
- the event data is len_in_next_word - 4
