qemu: Remove stray .git files after unpacking

The qemu tarball ships some extraneous .git metadata in the dtc/ and pixman/
subfolders, containing a reference to the path "../.git/modules" which
doesn't exist.  The presence of these files will confuse git if it happens
to recurse into the qemu source folder during an operation on some parent
directory, for example "git clean" at a higher level.  Avoid that problem
(mostly) by removing them immediately after the sources are unpacked.
