Follow-up to #4949: don't delete the current working directory

[jhpalmieri]

On Solaris, running rm -rf DIR fails if DIR is in the path of the current working directory. This happens in sage-spkg, so the temporary build directories $SAGE_BUILD_DIR/$PKG_NAME don't get deleted. Fix this by running cd ... first.

Could you just add a comment like

# On Solaris, the current working directory cannot be deleted,
# so we "cd" out of $SAGE_BUILD_DIR/$PKG_NAME, see #12637.

Done. (Also changed the name of the patch file to match the ticket number.)
