Bug 1249103 - remove support for MOZ_POST_DSO_LIB_COMMAND; r=mshal

Nothing uses this variable.  blame suggests that it was used for HP-UX
once upon a time.  The companion variable, MOZ_POST_PROGRAM_COMMAND, is
only used by HP-UX, but as we're not wholesale removing HP-UX
support (yet), we should leave MOZ_POST_PROGRAM_COMMAND alone.
