makepkg: add pkgbase variable

The pkgbase variable is added to improve informational output and
source package naming when using split packages.  Defaults to
${pkgname[0]} if not set.

Also:
 - move splitpkg detection to after pkgname presence is verified
 - add "cd" line to package_foo() functions in splitpkg proto
