templatefuncs: do not stringify result of if*() expression

Returning a generator means that the result is a byte string. I can't find
any reason to make the "if" condition lazy since it is evaluated anyway
when {if()} has to be evaluated. So let's simply make if*() return an input
expression unmodified.

#require test-repo execbit

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ cd "`dirname "$TESTDIR"`"

look for python scripts without the execute bit

  $ testrepohg files 'set:**.py and not exec() and grep(r"^#!.*?python")'

look for python scripts with execute bit but not shebang

  $ testrepohg files 'set:**.py and exec() and not grep(r"^#!.*?python")'

look for shell scripts with execute bit but not shebang

  $ testrepohg files 'set:**.sh and exec() and not grep(r"^#!.*(ba)?sh")'

look for non scripts with no shebang

  $ testrepohg files 'set:exec() and not **.sh and not **.py and not grep(r"^#!")'
