[PATCH] BaseTools: Add support for dots in paths

[Matthew Yeazel <yeazelm@amazon.com>]

The split assumes that there isn't a dot in the path to the file but
this isn't always the case. This will support more diverse paths.

Contributed-under: TianoCore Contribution Agreement 1.1
    Note: Section 3, paragraph 1, is read as an OR.
