perf: Use read() instead of lseek() in trace_event_read.c:skip()
This is a small fix for a problem affecting live-mode, introduced
recently:
root@tropicana:~# perf trace rwtop
perf trace started with Perl
script /root/libexec/perf-core/scripts/perl/rwtop.pl
Fatal: did not read header event
commit d00a47cce569a3e660a8c9de5d57af28d6a9f0f7 added a skip()
function to skip over e.g. header_page, but this doesn't work for
live mode. This patch re-implements skip() to use read() instead of
lseek() to fix that.
