Update .SRCINFO parser

Some arrays may be provided by both pkgbase and pkgname. The following
rules are applied now:

1. When pkgname has array items, array items from pkgbase are ignored.
If pkgname provides only empty items (e.g. "group = "), that means array
was erased for this pkgname in PKGBUILD.

2. The following arrays are extracted from pkgbase only: validpgpkeys,
makedepends, checkdepends.

3. If pkgname's depends array is less that pkgbase's depends array,
all missing items are considered as makedepends. For instance,
pkgbase:depends=(p1 p2), pkgname:depends=(p1), then p2 becomes
make dependency for pkgname.
