FS#15448 (which is made worse by the "fix" for FS#14727...), highlighted
some deficiencies in the usage of the BUILDSCRIPT variable. In particular,
only relative paths worked with "-p" and some output was very strange in
combination with the "-p" flag or reading from /dev/stdin. e.g.
"Please add a license line to your /dev/stdin!".

This patch adds a new variable, BUILDFILE, which contains the full path
to the BUILDSCRIPT.  This defaults to $startdir/$BUILDSCRIPT.

Also, fix a missed quoting of $BUILD{SCRIPT->FILE} and remove warning
about missing BUILDSCRIPT definition in makepkg.conf as the default
BUILDSCRIPT value is not specified during configure. Add check that
BUILDFILE is writeable before udpating VCS PKGBUILDs. When making a source
package, the BUILDSCRIPT always gets given the default name, regardless
of what it was originally called.
