Evgenii Alekseev d6cdb5bea5 fix: fix pkgbuild parsing in some cases
It has been found that there are two cases in which pkgbuild was not
parsed correctly

1. Major case in which there is quotation mark inside comment line,
   which would cause ValueError: No closing quotation error
2. Minor case, if there are utf symbols in pkgbuild file (e.g.
   hieroglyphs, see ttf-google-fonts-git), it will case incorrect
   reading in `_is_escaped` method
