I've found that sometimes it might be convenient when writing a test to not
put anything after all sections data. Currently we write the section header
table there.

This adds the `Location` sub key to `SectionHeaderTable` key:

  SectionHeaderTable:
    Location:  <value>

Location can be either `AfterSecData` or `BeforeSecData` currently.
This allows to place the section header table before sections data.

This patch also opens road to implement placing the section header table at
an arbitrary position (i.e. between sections).
