Makefile: handle broken curl version number in version check

curl 7.11.0 through 7.12.2 when built from their official release
archives will present a 5 digit version number instead of the documented
6 digits which breaks the version check in the Makefile.
Correct these broken version numbers on the fly when extracting them to
ensure the comparison works correctly.

[jc: shortened the new sed scripts a bit]
