Emacs OSX : package disk image too small

Emacs OSX : package disk image too small

[Sebastien Kirche]

Here is the end of a "make-package --self-contained"
compilation on my 10.2.5 system,
it seems that the make-package script builds a too
small disk image file...
the line 390 of the script is concerned :
sectorsAlloced=`echo 2*${compressedSize}+20|bc`
i tried to replace the 2 times multiplier by a 3 with
success, but that value should be fine tuned, as we
get a 37 MB file instead of 25 MB...

Multiplying by 3 is too much and unwarranted.  The following patch
multiplies by 2.1, to provide an extra 5% for use by directories and
partition tables on the disk image, and removes the additional `20'
sectors.  It has been checked it.
