bash_aliases: Remove grep_syscall(), grep_syscall_def(), and grep_glibc_prototype()

The functionality of those shell functions is covered by the grepc(1)
program: <http://www.alejandro-colomar.es/src/alx/alx/grepc.git/>.

The program has several bug fixes that these shell functions didn't
receive.  It also has more useful features.
