Arnaldo Carvalho de Melo 19ce232173 perf flamegraph: Use /bin/bash for report and record scripts 
As all the other tools/perf/scripts/python/bin/*-{report,record}
scripts, fixing the this problem reported by Daniel Diaz:

  Our OpenEmbedded builds detected an issue with 5287f92692 ("perf
  script: Add flamegraph.py script"):
    ERROR: perf-1.0-r9 do_package_qa: QA Issue:
  /usr/libexec/perf-core/scripts/python/bin/flamegraph-report contained
  in package perf-python requires /usr/bin/sh, but no providers found in
  RDEPENDS_perf-python? [file-rdeps]

  This means that there is a new binary pulled in in the shebang line
  which was unaccounted for: `/usr/bin/sh`. I don't see any other usage
  of /usr/bin/sh in the kernel tree (does not even exist on my Ubuntu
  dev machine) but plenty of /bin/sh. This patch is needed:

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
