ucb: FTP UCP: report CURLE_URL_MALFORMAT as IllegalIdentifierException

With curl 7.86, the test JunitTest_ucb_complex starts to fail:

.ftp://noname:nopasswd@*nohost.invalid
now executing open
com.sun.star.ucb.InteractiveAugmentedIOException:
	at com.sun.proxy.$Proxy15.execute(Unknown Source)
	at complex.ucb.UCB.executeCommand(UCB.java:63)
	at complex.ucb.UCB.checkWrongFtpConnection(UCB.java:119)

because curl_easy_perform() now returns CURLE_URL_MALFORMAT where
previously it was CURLE_COULDNT_RESOLVE_HOST.

Map this to an exception the test expects.
