[pass] ignore previous gpg4win patch, this one contains an additional fix

[Lenz Weber]

this works now with gpg4win converting cygwin paths to windows paths. 
I had to change an "exec $GPG" to "$GPG" as exec will not execute a function. please check if this impacts any behaviour

additional minor fix: gpg_winpath will apply to nonexisting output files now as well. calling "generate" would fail before
