oe-pkgdata-util: improve command-line usage

* Use argparse instead of optparse for standardised help output, options
  and a much cleaner code structure
* Look up pkgdata directory automatically so the user doesn't have to
  specify it
* Use standard logging

NOTE: this does mean a slight change in syntax - if you do want to
specify the pkgdata directory (usually only necessary if you're calling
it from within the build process) you need to use the parameter -p (or
 --pkgdata-dir) and specify this before the command, not after it.

Examples:

oe-pkgdata-util find-path /sbin/mke2fs
oe-pkgdata-util lookup-recipe libelf1
oe-pkgdata-util read-value PKGSIZE libc6
oe-pkgdata-util -p /home/user/oe/build/tmp/sysroots/qemux86-64/pkgdata read-value PKGSIZE libc6
