[PATCH] notmuch-mutt: replace gnu sed and xargs with perl

[Taylor Carpenter]

External software dependencies removed: sed and xargs.

Sed shell escaping is handled automatically with perl symlink function.

The xargs usage is specific to gnu xargs (fails on bsd xargs, etc).

NOTE: The current query pulls the list of files into an array all at
once.  The larger the list the more memory used.
