Subject: [PATCH] fix read-only gifs and math directories

An installed copy of stex might have all write permission bits removed,
even for the owner of the installed files: this is the case with Guix
package of stex, for example. If such an installation is used to
initialize the gifs or math directories (e.g. for an out-of-source
build), tar likewise creates them without write permissions, preventing
subdirectories from being created later. Set the user write bit
explicitly to avoid this problem.
