[Tim Rühsen]

The ASAN report was:
pkl-env.c:74:12: runtime error: implicit conversion from type 'unsigned long'
of value 591105371825 (64-bit, unsigned) to type 'int' changed the value to
-1600115023 (32-bit, signed)

2020-05-17  Tim Rühsen  <address@hidden>

        * libpoke/pkl-env.c (hash_string): Suppress ASAN runtime error
        "implicit-signed-integer-truncation-or-sign-change".
