Further bug fixes for enable/disables DEF files mechanism on Symbian

Fix bug where all target types, including apps, plugins and static
libraries were getting DEFFILE statements - now it's just libraries that
get it.

Fix bug where duplicate DEFFILE blocks were being added to projects that
manually specified their own DEFFILE - this now tests for the qmake
variable "defBlock" being set, and doesn't add additional DEFFILE
statements if it is.
NOTE: This means that adding DEFFILE statements to MMP_RULES
manually should be done by creating a variable called defBlock, and
adding that to the MMP_RULES (ie. MMP_RULES += defBlock)

Fix bug in configure.exe, where using -nokia-developer for Windows builds
would warn about Symbian DEF file usage (or lack thereof)
