perf test: Add pipe output testing for annotate

Parameterize the basic testing to generate directly a perf.data file
or to generate/use one from pipe input or output. To simplify the
refactor move some of the head/grep logic around. Use "-q" with grep
to make the test output cleaner.

perf/test: Speed up test case perf annotate basic tests

perf test 70 takes a long time. One culprit is the output of command
perf annotate. Per default enabled are
- demangle symbol names
- interleave source code with assembly code.
Disable demangle of symbols and abort the annotation
after the first 250 lines.

This speeds up the test case considerable, for example
on s390:

Output before:
# time perf test 70
70: perf annotate basic tests : Ok
.....
real 2m7.467s
user 1m26.869s
sys 0m34.086s
#

Output after:
# time perf test 70
70: perf annotate basic tests : Ok

real 0m3.341s
user 0m1.606s
sys 0m0.362s

perf test: Speed up test case 70 annotate basic tests

On some s390 linux machine (mostly older models) and with debug
packages installed, the test case 'perf annotate basic tests' runs
for some longer time.
Speed up the test and save the output of command perf annotate
in a temporary file. This is used to perform pattern matching via
grep command. This saves on invocation of perf annotate which
runs for some time.

Output before:
# time bash -x tests/shell/annotate.sh >/dev/null 2>&1; echo EXIT CODE $?

user 3m19.442s
