makepkg: make in-place sed portable

Do a sed replacement in-place is not very portable.  On Mac OSX and
BSDs, the syntax is "sed -i ''" where as with GNU sed the command is
"sed -i''" or just "sed -i".  This patch detects which command should
be used during configure.

Credit to Kevin Barry who researched this issue and provided a patch
to work around this using temporary backup files.
