Add some debugedit tests.

debugedit didn't have any direct tests, it was only tested indirectly
through some other debuginfo testcases.  So add some testcases that
just test debugedit functionality directly.

The tests create different kinds of ELF files (object files, partially
linked files and executables) and run debugedit path replacements on
them, checking that the resulting .debug_str, .debug_info and .debug_line
sections look sane.

Testcases verified against various different gcc and binutils versions.
gcc 4.8 and gcc 6 generate slightly different .debuginfo

Also add debugedit --version. Which makes it easy to see we are
testing the correct version/install of debugedit in rpmtests.log.

Adjust autotest paths to include rpmlibexecdir, where debuginfo
is installed.  Note that rpmlibexecdir != libexecdir (see rpm.am).
