utils: Remove security_context_t casts for libselinux >= 2.3
security_context_t has always been a typedef for char * and used more
or less interchangeably with char *, but the use of a typedef turned
out to be bad for const-correctness. The function signatures were
changed to take const char * in libselinux 2.3, in 2014[1] and the
typedef was formally deprecated in 2020[2].
On very old OSs like Ubuntu 14.04, reinstate the casts to suppress
warnings from -Wdiscarded-qualifiers.
