dev-tex/minted: fix compilation of documentation

Compiling of documentation currently failed, as -shell-escape was not
passed to pdflatex. With recent change in latex-package.eclass
(f6082c5) it is now possible to add this flag and therefore compile the
documentation.
Moreover in minted-2.1 there is an extra curly brace in minted.dtx which
leads to a compile failure also with -shell-escape specified. Until it
is fixed upstream, I added a patch to remove this extra curly brace.

Closes: gentoo#986

It would be possible to strip the wrapping quotation marks when they are present, and maintain any spaces in the file name. But it is simplest to create a ``sanitized'' version of |\jobname| in which spaces and asterisks are replaced by underscores, and double quotes are stripped.
