    AXIS2C-1567: Fix F_OK/R_OK undefined on macOS builds
    
    The unistd.h include was incorrectly excluded on Apple platforms with
    #ifndef __APPLE__, but the F_OK, R_OK, W_OK, X_OK constants from that
    header were still being used, causing compilation failures on macOS.
    
    Fix:
    - Remove the incorrect #ifndef __APPLE__ exclusion
    - Add fallback #ifndef definitions for all access() mode constants
    - Use standard POSIX values (F_OK=0, X_OK=1, W_OK=2, R_OK=4)
    
    The fallback approach is defensive - if unistd.h provides the constants,
    they're used; otherwise the standard POSIX values are defined.
