[pacman-dev] [PATCH 2/7] libmakepkg: stop printsrcinfo generating empty values

[morganamilo]

When a split package overriddes an array using += and the array does not
exist globally, makepkg --printsrcinfo will print the field with an
empty vlaue before printing the acual values.

For exampple: having `depends+=(foo bar)` will generate:
	depends =
	depends = foo
	depends = bar

Explicity check for empty array values and only print the values that
are not empty.
