scripts/oe-pkgdata-util: improve help text and command line parsing 

* Use optparse to parse command line
* Make help text actually helpful by describing what each command does
* Drop comment at the top listing the commands which is now superfluous

(From OE-Core rev: feb317513fff638ad7abdba8ab34b8413f0ab055)

# Currently only has two functions:
# 1) glob - mapping of packages to their dev/dbg/doc/locale etc. counterparts.
# 2) read-value - mapping of packagenames to their location in
# pkgdata and then returns value of selected variable (e.g. PKGSIZE)
# Could be extended in future to perform other useful querying functions on the
