libsmack: parse whole access type string, not only first 5 bytes.
libsmack: parse whole access type string, not only first 5 bytes.

Previous version of this function parsed only first ACC_LEN (5)
characters of access_type. Now the whole string will be read.

This will prevent silent ignoring of access type characters in cases
like "-rwxat" or "rrwxat".

Re-applying because it was reverted by d2283792.
