makepkg: optimize and fix BUILDINFO generation's use of awk
The biggest issue is directly supplying the data within the format string which can result in misinterpreting formatter sequences if a printed variable contains an "%" in it. This character is currently permitted in the pkgver field, though not in the pkgname. Also pacman/libalpm itself has much looser limitations and this can appear anywhere at all if a package was created by some other program. For the package "iambroke-1%s-1-any.pkg.tar.xz", installed in the build environment, the result is: -> Generating .BUILDINFO file... awk: cmd. line:3: (FILENAME=- FNR=1085) fatal: not enough arguments to satisfy format string `-1%s-1' ^ ran out for this one Followed by a .BUILDINFO which contains an LC_ALL=C sorted list of $pkgname-${epoch:+$epoch:}$pkgver-$pkgrel-$arch ending in: installed = iambroke Which is cut short, then fails to list the succeeding packages. The package itself successfully builds. It's also unnecessary to save the output of pacman -Qq in order to get the information for pacman -Qi, since the latter will, just like the former, return information for all installed packages if not given a package name(s). While I am at it, pipe this directly to awk rather than keeping a copy in an unnecessary local variable. This is slightly more efficient in addition to preventing the <<< herestring from re-interpreting the content of "$pkginfos" in ways that don't really matter for our usage.
