read-cache: remove redundant extern declarations

Browse Source 
The 'read-cache.c' file already includes 'environment.h', which provides
the extern declarations for variables like 'trust_executable_bit' and
'has_symlinks'.

Remove the redundant extern declarations inside 'st_mode_from_ce()' to
clean up the code.
