syscalls/quotactl: Don't use ltp-quota.m4

Current quotactl01.c has logic problem. There is no relation between
Q_GETINFO and quota format. The format should depend on quotacheck -F
and kernel config such as CONFIG_QFMT_V1 or CONFIG_QFMT_V2 (most linux
distributions use the v2).

Q_GETINFO cmd was introduced since Linux 2.4.22, we don't need to
check it now. Also, specify quota format to QFMT_VFS_V0 by quotacheck
-F and check CONFIG_QFMT_V2 in kernel config to avoid issue such as linux-test-project#189 [1].
So in quotactl01.c, we don't need to use the macro of ltp-quota.m4.
In quotactl0[2-3].c, we don't need to check very basic header <sys/quota.h>
(it was introdued in glibc since 1997). Remove quota version macro.

Don't remove ltp-quota.m4 because I will rewrite it to detect
if_nextdqblk struct for Q_GETNEXTQUOTA cmd on the coming patch.
