Revert "Allow 'make distclean' to clean up the 'generated' phar.inc"

This reverts commit 017145bc57e604153f2a2400dd6e73a397f52f96.
Clean up the 'generated' phar.inc file.
When building outside the source tree the copied phar.inc needs to be removed,
but when building in the tree, the file must remain since it is part of the source.
See the copying logic in ext/phar/Makefile.frag.
