Convert ALLOC_FAIL macro into a function

This path is rarely (read: never) taken in any normal run of the code,
so injecting the fprintf() call everywhere with the macro is a bit
overkill. Instead, add a lightweight _alpm_alloc_fail() function that
gets called instead.

This does have a reasonable effect on the size of the generated code;
most places using the macros provided by util.c have their code size
reduced.
