pkg/smbios: add SMBIOS package

This adds a new SMBIOS package which contains common structures from
SMBIOS as well as corresponding parsers.
I originally explored an approach where I manually designed optimized Go
types for each structure, but that would have led to a huge amount of
code that reading a structure of this type would cause if done
literally. I also considered code generation, but if the generated types
are to be close to the manually-designed ones it would be an incredibly
complex piece of code as well.
Finally I went with a design based on reflection which is much more
compact than the first two and consists of plain Go code at the expense
some niceness in the types.
I called the current types SomeTypeRaw in case I want to come back later
introduce a small layer mapping the current structures into nicer ones.
But for our current purposes the raw ones are good enough already.

This has been tested against our deployment targets, but as the SMBIOS
data contains uniquely identifying information these small tests are not
part of this CL. Sadly I haven't found any public SMBIOS test-cases.
