strace 5.4 released

[Dmitry V. Levin]

Starting with version 4.13, strace follows the schedule of linux kernel
and new versions of strace are released along with new versions of linux
kernel, so strace 5.4 is tagged and uploaded.

strace 5.4 would not be as good as it is without significant assistance
by Eugene Syromyatnikov.

$ git tag -v v5.4 2> /dev/null | sed -n '/^$/,$p'
