[GWP-ASan] Fix bugs in realloc().
Two edge cases were found in aosp/2038947:
1. realloc(p, 0) == free() and returns nullptr. Previously, we just
returned a new pointer.
2. If the malloc() part of realloc() fails (e.g. when the size of the
allocation is 1 << 56), then the old memory shouldn't be destroyed.
Bug: N/A
Test: Covered using atest bionic-unit-tests using aosp/2038947.
