program: rename bytecode load/write functions, track path of executed file

Extend source objects with a `runpath` field which contains the original
path of the source being executed by the VM.

When instantiating source objects from file paths, the `runpath` will be
set to the `filename`. When instantiating source buffers using
`uc_source_new_buffer()`, the runpath is initially unset.

A new function `uc_source_runpath_set()` can be used to adjust the runtime
path being associated with a source object.

Extend bytecode loading logic to set the source buffer runtime path to the
precompiled bytecode file path being loaded and executed. This is required
for `sourcepath()` and relative paths in `include()` to function correctly
when executing precompiled programs.

Finally rename `uc_program_from_file()` and `uc_program_to_file()` to
`uc_program_load()` and `uc_program_write()` respectively since the load
part now operates on an `uc_source_t` input buffer instead of a plain
`FILE *` handle.

Adjust users of these API functions accordingly.
