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.
