devel/svn2git: update to 1.0.12

• add LICENSE_FILE as it is now included in the tarball
• LICENSE does not indicate "or later" for version
• add libapr as dependency, it is linked in
• switch to Qt5 [1]
• override LOCALBASE for SVN and APR includes using qmake arguments
• update patches (and patch name)

[1] Although the code base still compiles with Qt4, the src.pro file
implicitly uses Qt5. On Qt4 the overriding of the SVN_INCLUDE and
APR_INCLUDE variables do not work (due to the src.pro implicitly using Qt5).
