[PATCH] sim: constify sim_write source buffer

[Mike Frysinger <vapier@gentoo.org>]

Most the sim write functions declare their source buffer const because
they only ever read from it.  The global sim_write() function does not
follow this convention though which causes some warnings when trying to
pass it const strings or buffers.
