pmbootstrap did not detect, that the `libsamsung-ipc` pkgver was invalid

Created by: ollieparanoid

#854 implemented validating pkgver after parsing APKBUILD files. But for this version...

$ grep '^pkgver=' aports/main/libsamsung-ipc/APKBUILD
pkgver=6.0_0002

...pmbootstrap does not complain, but apk does (when you try to build in --strict mode).

I will fix the pkgver for that package, but this issue needs to be fixed in pmbootstrap as well.
